Performance Analysis of Quorum Based Power Saving Protocols for Ad hoc Networks

Energy is a heart of ad hoc networks. The lifetime of the network depends on the durability of the mobile node’s battery power. Many energy conserving schemes are used to improve the energy efficiency and prolong the operational time of the mobile stations. Among these schemes Quorum based power saving protocol provides better energy conservation. In existing QPS the cycle length is identical to all the stations. The amount of conserved energy is also low. To overcome this we propose a new scheme called Hyper quorum system (HQS). In this it uses an arbitrary cycle length for as stations to maximize the energy efficiency and reduce the overall delay. Simulation results showed that the benefits of HQS over existing QPS.
