Authors: Roy Friedman Guy Korland

Abstract: Energy e±ciency and collisions avoidance are both critical properties to increase the lifetime and effectiveness of wireless networks. This paper proposes a family of algorithms for reducing both energy consumption and packets collisions in ad-hoc networks. In particular, this family of protocols offers a tradeoff between bandwidth utilization and power consumption. The proposed algorithms are based on geographic knowledge to form a virtual grid and on synchronized clocks in order to achieve a collision free locally computable transmission schedule. As an added benefit to the proposed approach, a new efficient location service that is adjusted to the grid oriented geo-routing is also presented. The paper analyzes the proposed family of algorithms for their induced latency and the energy vs. latency tradeoffs they provide.
