Abstract
A MANET is a type of ad-hoc network that can change locations and configure itself on the fly. A MANET involves mobile platforms which are free to move arbitrarily and there may be frequent link breakage due to battery. We propose a novel adhoc routing protocol named as Sector based Energy Efficient (SEA) routing protocol with high data throughput. To overcome the link breakage in MANET, the proposed protocol also uses the mathematical geometrical progression method, which minimizes the redundancy distance calculation and routing overhead. We also combine the mathematical model with weight based route estimation techniques. It selects the longest life span to estimate the route stability derived from received signal strength. The simulation results shows that the proposed SEA protocol yields better performance then the existing protocols namely EDRP, EDNR, DOA and AODV in terms of packet delivery ratio and energy consumption.
Highlights
Mobile ad hoc network consists of mobile nodes which are moving arbitrarily in a terrain space with limited or no-infrastructure
Sector based energy efficient adaptive routing protocol: Sector based Energy Efficient (SEA) is an energy efficient adaptive routing protocol that concentrates on a specified sector and minimize the frequent distance calculation using infinite geometrical progression provided by a location service (Hu and Fei, 2010)
It selects the least dynamic route with the longest lifespan for persistent data forwarding and coordinates the source, destination and the current node that points the packet to the destination, number of nodes participating in the route discovery will be reduced and reduces the routing overhead, Correlation failure and total energy consumption Fig. 1 shows the participating of nodes in the network
Summary
Mobile ad hoc network consists of mobile nodes which are moving arbitrarily in a terrain space with limited or no-infrastructure. The characteristics of MANET includes dynamic topology, battery constrained and, limited resources. Developing routing protocol with reduced overhead towards improving reliable communication assurance is a major thrust research area in MANETs (Martin et al, 2007). Link failure which is the outcome of dynamic topology is one of the main reasons that results in frequent route failures and path reconstruction. A new algorithm to evaluate the node lifetime and the link lifetime utilizing the dynamic nature such as the energy drain rate and the relative mobility estimation rate of nodes. The radio range is limited and extending the range will not be the right solution. Due to all these above said factors the packet delivery ratio and throughput is decreased and end-toend delay is extended
