An Optimized Mechanism for Adaptive and Dynamic Policy Based Handover in Clustered MANET
On-going revolution in ever-improving wireless communication enforces the necessity of a self configuring, rapidly deployable and infrastructure less network. MANET is such an autonomous wireless network that meets the requirements. At the same time MANET's random behavior and absence of any central intelligence to gather unambiguous knowledge about user contexts complexes QoS maintenance and hampers proper utilization of network resources resulting into unnecessary handovers. In past, few policy driven handover approaches have been proposed for MANET but none of them explores a comprehensive policy design. Therefore in this paper, the authors propose an adaptive and optimized policy based handover mechanism which is based on explicitly designed policies like load balancing, service discovery and next hop selection. Efficient procedures for these policies are also explored.
