Design Considerations of MoHotS and Wireless Chain Networks 总被引:1,自引:1,他引:0
Johnson I. Agbinya 《Wireless Personal Communications》2007,40(1):91-106
This paper introduces and discusses MoHotS and wireless chain networks. The paper proposes integration of unused capacity in hot spots. We discuss the area of coverage and the probability of making connections in wider area wireless networks based on MoHotS. The area of coverage of MoHotS is evaluated for MoHotS on highways. It also addresses the limits of interference in networks of wireless MoHotS and chain networks. It is shown that the interference from other MoHotS converges for large N and is tamed by the path loss exponent. Terrain characteristics are described as well.

Wireless sensor networks are increasingly deployed in security-critical areas, such as battle field. However, general sensor nodes are manufactured with inexpensive components, and they are short of security enhancement. Therefore, an adversary could capture and compromise sensor nodes easily, then launch some malicious attacks (including tampering or discarding useful data collected from source nodes). In this paper, we propose a secure routing and aggregation protocol for sensor networks, which utilizes one-way hash chain and multi-path mechanism to achieve security of wireless sensor networks. 相似文献
