On Enhancing Event-to-Sink Data Delivery Throughput in Sensor Networks
The many-to-one multihop traffic pattern of Wireless Sensor Networks (WSN) puts a great challenge on enhancing the event-to-sink data delivery throughput. Because, in CSMA/CA dri...

Re-routing Instability in IEEE 802.11 Multi-hop Ad-hoc Networks
TCP throughput instability is a well-known phenomenon in IEEE 802.11 multi-hop ad-hoc networks. However, we find that this problem is not restricted to TCP traffic only, but also ...
