An Efficient Routing Protocol for Delay Tolerant Networks (DTNs)
Delay-Tolerant Networks are those which lack continuous communications among mobile nodes. Distributed clustering scheme and cluster-based routing protocol are used for Delay-Tolerant Mobile Networks (DTMNs). The basic idea is to distributive group mobile nodes with similar mobility pattern into a cluster, which can then interchangeably share their resources for overhead reduction and load balancing, aiming to achieve efficient and scalable routing in DTMN. Load balancing is carried out in two ways, Intra cluster load balancing and Inter cluster load balancing.
