SPSR: A Lightweight Secure Proactive Source Routing Protocol for Mobile Ad-Hoc Networks

Opportunistic forwarding, by which data is randomly relayed to a neighbor based on local network information, is a fault tolerant distributed algorithm particularly useful for challenged ad-hoc and sensor networks. Opportunistic data forwarding has drawn much attention in the research community of multi-hop wireless networking and more researches are conducted for stationary wireless networks. The reason why opportunistic data forwarding is not utilized in Mobile ad-hoc networks is lack of an efficient lightweight secure proactive source routing (SPSR) scheme with strong source routing capability. A lightweight secure proactive source routing (SPSR) protocol is proposed where SPSR protocol has much smaller overhead, less end to end delay and energy consumption and increase in throughput and packet delivery ratio (PDR). The SPSR protocol is compared with the traditional OLSR protocol for the performance analysis. The tests using computer simulation are conducted in Network simulator version-2 (NS-2) and the appropriate graph is shown.
