— The IEEE 802.16j protocol for a multi-hop relay (MMR) WiMAX network is being developed to increase data rates and extend service coverage as an enhancement of existing WiMAX st...
— The recent advances in wireless sensor technologies (e.g., Mica, Telos motes) enable the economic deployment of lightweight sensors for capturing data from their surrounding en...
Overlay networks have been very useful in solving large scale data dissemination problems. In this paper, we consider the case of data gathering which is the inverse of disseminat...
Abstract-- We present a novel formulation of the problem of energy misbehavior and develop an analytical framework for quantifying its impact on other nodes. Specifically, we formu...
