Abstract:
1. A clustering based load adaptive sleeping protocol for ad hoc networks, comprising: a beacon signal originating from a cluster-head of a cluster, said beacon signal comprising a plurality of sequential beacon intervals, said beacon intervals each comprises a plurality of time slots associated with groups of nodes in said cluster; wherein said groups of nodes are defined by node_id modulo n, where node id represents a unique host identification of each node, and n is an integer representing a number of groups in said cluster; wherein said time slots are sequentially numbered zero to n−1; wherein each said beacon interval comprises at least one sequence of time slots numbered zero to n−1; and wherein one of said n time slots represents an epoch when a node is in an awake state, and n−1 time slots represent an epoch when said node is in a sleep state.
