Interference is one of key factors of performance degradation in wireless communications. Various interference models have been proposed in the literature. However, most of them did not take node mobility into account. In fact, as an interferer approaches a carrier sensing range due to node mobility, the transmitted frame may also encounter a collision. Due to the interfering source, it is necessary...
Motivated by applications in industrial communication networks, in this paper we consider the trade-off between relationship anonymity and communication overhead in anonymity networks. We consider two anonymity networks; Crowds that provides unbounded communication delay and Minstrels, proposed in this paper, that provides bounded communication delay. While Crowds hides the sender's identity only,...
Collision mitigation is one of classical research issues for wireless local area networks (WLANs). Recently, multiple-input multiple-output (MIMO) transmission techniques have been widely deployed in wireless systems, while a multi-user MIMO-based collision mitigation scheme in uplink WLANs was proposed by authors, and we showed the scheme is very efficient for the uplink performance. However, for...
In terrestrial-satellite hybrid networks, traditional TCP performance degrades a lot due to long propagation delays and high bit error rates link. Performance enhancing proxy(PEP) can shorten round trip time loop time and Peach can enhance the performance over high bit error rates link. In this paper, we propose a new scheme that combines PEP and TCP Peach for terrestrial-satellite hybrid networks...
