Overlay Wireless Sensor Networks for Application-Adaptive Scheduling in WLAN
نویسندگان
چکیده
Supporting application QoS in wireless environment remains a challenging task due to the inherent constraints of wireless interfaces (resource scarcity, signal quality, etc.). While current standards offer relative QoS through service class differentiation, assured QoS is still a critical requirement for supporting multimedia and real-time applications. In consideration for fairness and bandwidth utilization, we propose a twotier architecture wherein an overlay of sensor network acts as the control plane over existing 802.11 WLAN. Via simulations, we demonstrate the effectiveness of our architecture and its adaptability to application needs.

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
