Providing security services for wireless sensor networks plays a vital role in secure network operation especially when sensor networks are deployed in hostile areas. In order to p...
Convergecast is a fundamental operation in wireless sensor networks. Existing convergecast solutions have focused on reducing latency and energy consumption. However, a good desig...
This paper is concerned with coordinated delivery of messages in sensor networks. The notion of multicast is re-examined in light of a new set of requirements that are specific t...
Networks of wireless microsensors for monitoring physical environments have emerged as an important new application area for the wireless technology. Key attributes of these new t...
We present a simple model of self-organization for sensor networks that addresses two conflicting requirements: hazard situations should be reported to a sink node with as little ...
