In this paper, we argue that by carefully considering spatial reusability of the wireless communication media, we can tremendously improve the end-to-end throughput in multi-hop wireless networks. To support our argument, we propose spatial reusability-aware single-path routing (SASR) and anypath routing (SAAR) protocols, and compare them with existing single-path routing and anypath routing protocols,...
Opportunistic routing emerged as a novel technique to cope with the problem of highly unpredictable and lossy wireless channels in urban wireless mesh networks. However, existing opportunistic routing protocols only consider single-radio wireless nodes, and assume that all the nodes work on the same channel, without exploiting possible concurrent transmissions by multi-radio nodes over orthogonal...
In this abstract, we have studied the problem of channel assignment in multi-radio, multi-channel wireless mesh networks, considering the support of opportunistic routing technique. First, we have formally modeled the channel assignment problem. Second, we have presented our multichannel opportunistic routing protocol. Third, we have shown the infeasibility of traditional channel assignment schemes,...
Currently, several researches have concentrated on the new or vital security requirements of mobile commerce. However, some recent studies asserted a particular serious attack, called wormhole attack, that mainly targeting in a wireless-based system may also occur in the mobile commerce systems. Although there are many endeavors to confront wormhole attacks in the field of wireless communications,...
Multipath routing has long been studied as an important routing strategy in networks. Many multipath routing protocols schedule traffic among multiple paths in order to distribute traffic load. However, existing multipath routing protocols with traffic assignment require that all nodes in the network follow the protocol, which may not always be a valid assumption when the network consists of selfish...
