QoS Routing Algorithm with Sleep Mode in MANETs

Abstract

MANET became the focus of researchers as an assurance technology for a broad range of due to their self-managing and self-configuring multi-hop wireless networks since the nodes are mobile, the network topology may change rapidly and unpredictably over time. An ad hoc network, or MANET (Mobile Ad-hoc Network), is a network contain only of nodes, with no Access Point. One significant area of research within ad hoc networks is energy consumption concern. The primary aim of ad hoc networks is to call for the energy-constrained protocols. Energy consumption evaluation methodology is set up for the protocol consideration in different mobile network. AODV routing protocol carry out well on assessment of energy consumption for the mobile ad hoc network with high node mobility. Nodes in MANET networks are basically battery operated, and thus have way in to a limited amount of energy. This process recommended an Energy based Ad-Hoc on-Demand Routing algorithm that balances energy among nodes so that a minimum energy level is maintained among nodes and the lifetime of network is enhanced. This paper, aim on increasing the prolonged existence of node in the network in our proposed algorithm, QS (QoS Scheme for MANET’s), addresses the issue of energy consumption in a manner fair to all network nodes. In our proposed scheme “energy aware routing” QS is suggested to use. The QS makes sure the connected and neighboring nodes to use it as forwarding node. Also, it checks the node with higher energy to make it applicant for forwarding purpose. From a functional point of view, QS can be consisting of two main units: One of these units deal with the energy conservation operation. This is done through uphold the nodes’ threshold energy levels to minimize the packet loss due to link breaks. The other aspect of the algorithm takes care of connectivity using routing protocol. It helps to guarantee the routing protocol makes routing decisions that serve a specific goal. The construct of network scenarios and performance study is done on NS-2.34 to simulate both the AODV and AODV-Sleep under the similar scenario. This paper also compares and analyzes the simulation results with a popular on-demand routing protocol AODV to show the utility of this algorithm. From this simulation one finds that the overall MANET’s efficiency is maximized.
