Problem Analysis of Routing Protocols in MANET in Constrained Situation
A Mobile Ad-hoc NETwork (MANET) consists of a number of mobile wireless nodes, among which the communication is carried out without having any centralized control. MANET is a self organized, self configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The mobile nodes can receive and relay packets as a router. Routing is a critical issue and an efficient routing protocol makes the MANET reliable. The AODV outperform DSR in the normal situation but in the constrained situation DSR outperforms AODV, the degradation is as severe as (30%) in AODV whereas DSR degrades marginally (10%) as observed through simulation in Glomosim.
