Many of the routing protocols that have been designed for wireless ad-hoc networks focus on energy-efficiency and guaranteeing high throughput in a non-adversarial setting. Howev...
LEACH (Low Energy Adaptive Clustering Hierarchy) [1] is one of the popular cluster-based structures, which has been widely proposed in wireless sensor networks. LEACH uses a TDMA ...
AQM (Active Queue Management) mechanism is a congestion control mechanism at a router for controlling the number of packets in the router’s buffer by actively discarding an arri...
In this paper, ranging process in IEEE 802.16e OFDMA systems is analyzed and performance is evaluated. Ranging process provides initial network entry, uplink synchronization, and ...
Obtaining location information by localization schemes for sensor nodes makes applications of wireless sensor networks (WSNs) more meaningful. Most of localization schemes only us...
