Abstract
A mobile ad-hoc network (MANET) is a group of nodes that is an infrastructure less network and therefore can be easily installed and deployed instantly. The research activities in mobile ad hoc networks (MANET) are grown over the last few years. There are numerous challenges in designing a wireless ad hoc network like dynamic topology, limited and shared bandwidth and limited battery power. This paper concentrated on providing the solution for routing overhead and energy consumption. Due to dynamic nature of the nodes there may occur the path failures and lead to route discoveries. Due to changing topologies the route from source to destination breaks quite frequently.In this paper, we propose an efficient Hash table-based Node identity (HTNI) technique the use of which bandwidth for numerous flows may be reserved in such network environments. Bandwidth reservation relies upon at the form of the traffic and its priorities. We outline a bandwidth reservation aspect for use in such hybrid network environments. The cross-layer- based structure for bandwidth reservation to keep quality-of- service (QoS). We use a priority re- allocation method for flows which starve for long time. The proposed technique is beneficial for finding the location of nodes with low conversation value and we are considered the simple algorithm which will detect and prevent the malicious node in the route named as M-detection. This protocol has been implemented on NS-2 and results display that this protocol achieved better performance in terms of the packet delivery ratio, end-to-end delay and routing packet overhead when compared to current routing schemes in literature.
