Wireless sensor networks (WSNs) have been widely used in various applications for continuous event monitoring and detection. The WSNs communication is generally event-driven. While confidentiality of the message content can be ensured through content encryption, it is much more difficult to adequately protect the source-location information of the event. For WSNs, source-location privacy service is...
Cooperative communications achieve tremendous improvements in system performance. Meanwhile, it tends to change the conventional access and transmission schemes in wireless networks. Thus, CoopMAC is proposed and analyzed for fully connected WLANs. It improves the performance of the network dramatically by enabling additional collaboration from other nodes. However, how does it work in multi-hop Ad...
It is a big challenge to exploit multiple antennas for routing protocol design in ad hoc networks. In order to improve throughput in the networks, this paper proposes a newly designed self-adaptive source routing (MISR) protocol based on multi-links especially including the Group-MUX link with antenna selection scheme that could achieve both the multiplexing and diversity gains simultaneously. Through...
Topology control via per-node transmission power adjustment has been shown effective in extending network lifetime. However, most of existing algorithms construct static topologies which fail to consider the residual energy of network nodes, thus in fact they can not balance energy consumption efficiently. To address this problem, a lightweight distributed topology control algorithm EDTC (Energy-aware...
