Epidemic Routing with Agents in Intermittently Connected MANETs

Intermittently Connected Mobile Ad hoc Network (ICMANET) is a partially connected Mobile Ad hoc Network (MANET) and is a form of Delay Tolerant Network, where there never exists a complete end – to – end path between two nodes wishing to communicate. The intermittent connectivity araise when a network is sparse or highly mobile. Routing in MANET is achieved through many available traditional routing protocols like Ad hoc On demand Distance Vector (AODV), Optimized Link State Routing (OLSR), Zone Routing Protocol (ZP) etc. These protocols require a connected topology for successful data transmission. Due to the absence of constant connectivity, the traditional protocols are not suitable for routing. Routing in such a spasmodic environ is arduous too. Recent researchers have proposed many routing techniques for ICMNAET. It is evident that even though routing is possible in ICMANET, secure routing in such networks still remains an unanswerable issue. As a means of providing security in ICMANET, in this paper we proposed a secure routing technique. The secure routing is achieved by setting of agent at each node in the available Epidemic Routing Protocol. Setting agent at each node ensures a greater probability of security.
