Sensor networks are fundamentally constrained by the difficulty and energy expense of delivering information from sensors to sink. Our work has focused on garnering additional si...
In this paper, we address the problem of cross-layer optimization in medium access control (MAC) and network layers for wireless multicasting with multiple cooperative or competit...
A number of IEEE 802.15.4 devices can be connected by a tree topology as proposed by ZigBee specification. Address configuration in tree-based ZigBee networks needs to assign ever...
Routing has been the main challenge for ad hoc networks due to dynamic topology as well as resource constraints. Completely GPS free as well as GPS scarce positioning systems for ...
A number of IEEE 802.15.4 devices can form a tree topology as proposed by ZigBee specification. The ability to confine the shape and extent of the tree serves as the basis for add...
