ABSTRACT
The present work integrates mobile ad-hoc network, wireless local area network and cellular network. It balances the load among the three networks in the integrated heterogeneous environment. It uses a home agent for the selection of the optimal network depending upon the type of session of the mobile nodes. It uses route selection algorithm to select the optimal route in the selected optimal network. Two different position based ant colony routing algorithms are proposed for mobile ad-hoc network in the present work. Both the routing algorithms select an optimal route for a session before starting it. They use route maintenance algorithm to detect whether a node associated with an existing route is going out of the communication range during the ongoing session before the existing route fails completely. Such consideration helps to reduce the data packet loss for both the algorithm. Our previous route selection algorithm is used for route selection in the wireless local area network and cellular network. The performance of the proposed routing algorithms for mobile ad-hoc network are compared with the performance of the existing basic position based ant colony routing algorithm on the basis of initial path set up time, average delay and packet loss. The performance of the three networks is compared on the basis of path set up time and average packet delay in the integrated heterogeneous environment. The performance of the proposed integrated scheme is evaluated in terms of blocking probability.
