Abstract
A protocol for providing location-based communication services in wireless sensor networks utilizes dynamic selection of forwarding devices, dynamic forwarding decisions, and intelligent backoff. Dynamic selection of forwarding devices limits the number of transmissions by dynamically selecting the devices that forward a message. Dynamic forwarding decisions implement different heuristics for different devices. According to intelligent backoff, devices that are closer to a destination region backoff for a shorter period of time than those which are further away from the destination region.
