— Performance of Wireless Sensor Networks (WSNs) can be affected when the network is deployed under different topologies. In this paper we present a performance study of congesti...
Secure communication in wireless ad hoc sensor networks is a major research concern in the networking community. Especially the few available resources in terms of processing powe...
The common perception of public key cryptography is that it is complex, slow and power hungry, and as such not at all suitable for use in ultra-low power environments like wireless...
Abstract-- Wireless sensor networks (WSNs) require energyef cient protocols to improve the network lifetime. In this work, we adopt a cross-layer strategy that considers routing an...
