energy efficient communication for ad hoc wireless sensor networks pdf

... Revised 15 April 2005 Wireless ad hoc sensor networks differ from wireless ad hoc networks from the following perspectives: low energ y, lightweight routing protocols, and adaptive communication patterns. ... of ad hoc wireless sensor networks. EARP is well suited for sensor networks due to its ability to adapt to the environment and make routing decisions based on the 640 EURASIP Journal on Wireless ... communication patterns. This paper proposes an energy- aware routing protocol (EARP) suitable for ad hoc wireless sensor networks and presents an analysis for its energy consumption in various phases of...
