Cluster Based Routing Mechanism For Advanced Delay-Tolerant Networks

In this paper, the main goal is to group similar mobile nodes distributive into a clusters, which can then exchange and share their resources, and achieve proficient routing in DTMNs (Delay-Tolerant Mobile Networks) which may lack in network connectivity. It’sdifficult to use DTMN’s to establish the reliable connections for data delivery since it lacks in connectivity. Data transmission in a dynamic network like DTN to the destination node with less delay is the major problem to be addressed. Routing in DTMNs is based on nodal contact probabilities. So the basic idea is to utilize the nodal contact probabilities and form clusters. The cluster-based routing protocol is based on exponentially weighted moving average (EWMA) scheme is engaged for on-line updating nodal contact probability. Two Gateway nodes are selected for routing which acts as an interface between two clusters and performs data transmission. Simulations are carried out to evaluate the effectiveness and efficiency of the proposed cluster-based routing protocol. The result shows that the proposed system achieves higher delivery ratio and significantly lower overhead and end- to-end delay. Keywords-Clustering, Delay-tolerant networks
