Significant TCP unfairness in wireless local networks has been reported during the past several years. This unfairness results from the greedy TCP protocol and shared wireless medium. To solve the unfairness problem between uplink TCP flows, we proposed a scheduling algorithm called uplink weighted fair queueing (UWFQ). By adjusting the service weight of ACK packets, UWFQ achieves the channel adaptive...
Geographic routing is widely used in wireless sensor networks. The problem that most of the geographic routing algorithms, which adopt greedy algorithm as their basic routing strategies, have to face is the ldquolocal minimal phenomenardquo. In this paper, we propose a neighbors investment geographic routing algorithm (NIGRA), which is based on the geographic information of 2-hop neighbors. NIGRA...
