Abstract:
1. A method for establishing a communication path between a plurality of nodes in an ad-hoc multi-hopping network, comprising: determining a number of allowed transmission hops between nodes in a communication path for a communication traveling from a first node to a second node of said plurality and an optimum transmission power level at which at least one node is said communication path will use for transmission; locating said communication path between said first and second nodes by using at least one transmission at said optimum transmission power level from said first and second nodes and allowing nodes of said plurality of nodes to adjust transmission power levels at each node to maintain connectivity such that at least one of said first and second node remains at said optimum transmission power level; and modifying variables of said optimum transmission power level determination and repeating said communication path locating step if said number of allowed transmission hops are exceeded in said communication path.
