Abstract--Highly distributed environments such as pervasive computing environments not having global or broad control, need another attribute certificate management technique. For ...
We consider the problem of static transmission-power assignment for lifetime maximization of a wireless sensor network with stationary nodes operating in a data-gathering scenario...
In this paper, we propose a novel Geographic Multicast routing Protocol (GMP) for wireless sensor networks1 . The proposed protocol is fully distributed and stateless. Given a set...
Monitoring a distributed system to detect a stable property is an important problem with many applications. The problem is especially challenging for a dynamic distributed system b...
Answering aggregate queries like sum, count, min, max over regions containing moving objects is often needed for virtual world applications, real-time monitoring systems, etc. Sin...
