C-LOAD POWER CONTROL PROTOCOL-CROSS-LAYER DESIGN OF A NETWORK LAYER LOAD POWER CONTROL PROTOCOL IN WIRELESS AD HOC NETWORKS

Abstract

In wireless ad hoc network scenario, Cross-layer design is emerging, important in wireless ad hoc network and the power control methods. Power control is the intelligent selection of transmit power in a communication to achieve the better performance within the system. Cross-layer is used to sharing the information between the layers. Physical to Transport layer information are shared in this protocol, due to this cross-layering is designed to optimize the power control. CLD using LOADPOWER (LOADPOW) control protocol is reduce the overall end-end delay and the energy consumption using transmission power. The novelty of this work deals with both low and high transmission power control methodologies. So many power control schemes are dealt in MAC layer but this work, Power control protocol was done in network layer and it plays a vital role. A MAC approach to power control only does a local optimization whereas network layer is capable of global optimization. Simulation was done in NS-2 simulator with the performance metrics as improved throughput, energy consumption and end-end delay. The key concept is to improve the throughput, saves energy by sending all the packets with optimal transmission power according to the network load. A comparison of few protocols with Load Power Control Protocol (LPCP) was implemented and got the better performances using NS-2 simulator.
