RESEARCH FOCUS 
Rapid advances in modern high speed networks and wireless/Mobile networks, with the support of internet growth, have produced tremendous research and commercial opportunities in the area of mobile multimedia communications. Differentiated service or service subject to quality requirements and mobility of end users/terminals needs software and/or hardware support at both intermediate and end systems, i.e., routers, Mobile Switching Centers (MSC), Base Station (BS), etc. The increasing demand for such services has led to many new research topics such as resource management for quality of service (QoS), Admission Control, Location management, Routing and mobile computing for mobile multimedia networking. My research interests include Resource management, Admission Control, Location and connectivity management, Dynamic routing for mobile multimedia conferencing and the applications of Neural Networks (NNs) to solve optimization, prediction and classification problems arising in mobile multimedia networks. 

RECENT RESEARCH RESULTS

Resource management and Admission Control
In mobile networks the traffic fluctuation is unpredictable due to mobility and varying resource requirement of multimedia applications. Hence it is essential to maintain the traffic within the network capacity to provide the Service guarantees to running applications. In this work, we propose an Admission Control (AC) scheme in a single mobile cellular environment supporting real-time and non-real-time application traffic. In the case of a real-time and non-real-time multimedia applications, each applications has its own distinct range of acceptable Quality of Service (QoS) requirements (e.g., packet loss, delay, jitter, etc.). The network provides the service by maintaining the application specified QoS range. We propose a Linear Programming Resource Reduction (LP-RR) principle for admission control by maintaining QoS guarantees to existing applications and to increase the percentage of admission to real-time and non-real-time applications. Artificial Neural Networks (ANNs) are used to solve linear programming problem, which facilitates in real time control decision in the practical systems. The model is computationally less expensive and faster for resource allocation. The reason for the use of neural networks is based on the consideration that a hardware-implemented neural networks can get a solution in a few microseconds.

We present an analytical model and results for the proposed admission control scheme with resource reduction principle and a simulation study of the admission control for performance evaluation. The suggested scheme along with the LP-based resource reduction has shown that it is appropriate for the reduction of assigned resources for running applications during over load conditions and allocation of resources to requesting applications.


Prediction based Location Management
Location Management is one of the key issues in mobile networks to provide an efficient and low cost services. In this work, we propose a prediction based location management scheme for locating a Mobile Host (MH), which depends on its history of movement pattern. A Multi-layer Neural Network (MNN) model for mobile movement prediction is designed to predict the future movement of a mobile host. The MNNs are trained with respect to the time series data obtained from the movement pattern of a mobile host for making predictions. 

Connectivity Management for Mobile Computing Environment 
The mobile computing environment experiences wireless problems and suffers from limited bandwidth, which leads to frequent disconnections. This has posed a challenge in maintaining user-to-user connectivity and its management in the mobile computing environment. In this work, we propose a Neural Network (NN) based connectivity management for mobile computing environment by maintaining the status information of mobile hosts at the base station. Here, the connectivity management handles frequent disconnection of Mobile Hosts (MHs) which are occurred due to hand-offs and interruptions. The disconnection of a MH due to wireless problems is called interruption. The neural networks are trained with respect to the status information to provide an intelligent decision for the connectivity management. 

Reliable Multicast Routing in Mobile Networks: A Neural Network Approach
Mobile networks that handle multicast communication services, like video-on-demand, news-on-demand, etc., require a kind of reliable and secure point-to-point, point-to-multipoint specific group communications for sophisticated organization of multicast communications. A reliable multicast tree is an efficient connectivity between the source node and the multicast group members through the dependable hosts. Besides that the mobile host change their access point over time hence multicast routes must be updated. This poses several challenges to provide an efficient multicast routing. 

In this work we propose a Neural Network (NN) based multicast routing algorithm for constructing a reliable multicast tree that connects the participants of a multicast group. The problem is tackled by dividing a mobile network into clusters of nodes based on the adjacency relation between the nodes (Mobile Support Stations), by considering a suitable neighborhood distance. The center cluster, whose nodes are almost equidistance from the multicast group members, is computed to construct a shortest multicast tree that passes through the center cluster and reliable routers among all the group members. We have used a Kohonens self-organizing map Neural Network (KNN) for clustering.

Hopfield Neural Networks (HNNs) are used to construct a multicast tree with a minimum number of links and passes through the nodes that belong to center cluster. Also, the tree is constructed as and when the member(s) moves. This scheme should construct a reliable multicast tree and minimize re-computation time of the multicast tree as and when the multicast route is updated when the mobile hosts change their access point due to mobility. The algorithm can be extended for constructing reliable multicast trees for more than one multicast groups.


Protocol Engineering (Conformance test sequence generation) 
Conformance testing for communication protocols is to test whether a protocol under test, conforms to the specifications laid down during the design phase. The work that is carried out is, ''An optimal test sequence generation using Multiple Unique Input/Output sequences (MUIOS)''. Here, the test sequence generation problem using MUIOS is viewed as an asymmetric traveling sales person problem. This problem is solved by using a Hopfield Neural Network as an optimization model. This technique is applied to various test cases and the results are compared with the results obtained by using Chinese Postman Tour Algorithm.
