Varying interference levels make broadcasting an unreliable operation in low-power wireless networks. Many routing and resource discovery protocols depend on flooding (repeated per-node broadcasts) over the network. Unreliability at the broadcast-level can result in either incomplete flooding coverage or excessive re-flooding, making path maintenance either(More)
Data dissemination in sensor networks requires four components: resource discovery, route establishment, packet forwarding, and route maintenance. Resource discovery can be the most costly aspect if meta-data does not exist to guide the search. Geographic routing can minimize search cost when resources are defined by location, and hash-based techniques like(More)
—Simulation can be an important step in the development of software for wireless sensor networks and has been the subject of intense research in the past decade. The simulation software should account for all possible factors affecting the wireless sensor networks. In this study we have addressed the question of correlated loss in among the communicating(More)
