An Efficient Routing scheme for reliable path establishment among Mobile Devices in Heterogeneous Networks

In heterogeneous networks, devices available with varying connectivity help to provide many new opportunities for efficiently utilizing new resources. In mobile ad hoc networks with varying layered architecture, not much interest is given yet in establishing path among devices with increasing or decreasing in number of mobile devices in the network and the complexity in using them because of their mobility. In this paper, we have considered the various aspects of routing in order to find out the proper nodes in the network and establish a reliable link in a heterogeneous environment. A new Routing scheme called SFUSP (Self-eliminating Faulttolerant based Un-interrupted reliable Service switching mobile Protocol) is discussed which is specially designed for establishing path among devices in heterogeneous environment in pervasive spaces. Our routing scheme is based on proactive routing characteristics with further added dynamism in selecting better nodes in the routing path in the heterogeneous networks. Performance analysis of our routing scheme is compared to other existing manet protocols such as AODV, DSR and OLSR in Random Waypoint, Brownian and Manhattan mobility models under MAC layers IEEE 802.11, 802.15 and 802.16 for WIFI, WPAN and WIMAX networks. Our routing scheme shows better performance for the above mentioned standards and is well suited for pervasive environment. KeywordsManet, Self-elimination, WIFI, WPAN, WIMAX, MAC, pervasive.
