Issues and Imperatives of Adhoc Networks

Executive Summary

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 provision of Quality of Service (QoS) guarantees is much more challenging mainly due to node mobility and resource constraints. Security is an essential requirement in Mobile Ad-hoc NETworks (MANETs). Compared to wired networks, MANETs are more vulnerable to security attacks due to the lack of a trusted centralized authority and limited resources. In practice, most TCP deployments have been carefully designed in the context of wired networks.
