Recently, wireless sensor and actor networks (WSANs) have evoked attention because of its extensive application foreground. WSANs include resource-unconstrained nodes, actors, to make decisions and deal with gusty events. As we all know, one of the most important objectives of designing communication schemes for wireless sensor networks (WSNs) is to(More)
In wireless sensor and actor networks, many applications depend on position information of those sensors sensing the physical world. Many localization schemes have been proposed In WSNs or ad hoc, however, due to the difference between them and WSANs, these schemes may not be well suited for WSANs. In this paper, we analyze why the existing localization(More)
Recent advance in Wireless Sensor Network (WSN) has led to totally different applications which attract a lot of attention. As addressed in [8], how to energy-efficient routing data packets to multi-sinks is a big challenge in WSN. While distributed multicasting technology is the most likely way to cope with this problem in nature due to the special(More)
In some specific wireless sensor network (WSN) applications, multi-sinks support is absolutely necessary in protocol stack, especially in routing layer, for energy efficiency concern. Distributed multicasting technology is the most energy-efficient way to cope with this problem in nature. However, the traditional multicast tree structures usually require a(More)
Compared to uni-path routing, multi-path routing can better utilize network bandwidth and balance network traffic. These features make it more suitable for mobile ad hoc networks with dynamic network topology and limited network bandwidth resource. In terms of QoS, providing multi-path routing in networks can better support QoS. In this paper, we propose a(More)
Random deployment of sensors may induce blind paths problem in wireless sensor network. To some applications of WSNs, the existence of blind paths will endanger the networks. It is necessary to study and solve the blind paths problem. In this paper, we examine the blind paths in wireless sensor networks and advance a feasible solution to it
This paper surveys the comprehensive efforts made in the sphere of Internet raffic measurement and analysis. In the latter part of this paper, we descri be the architecture and methodology of FUNAP, anetwork traffic measurement, simulation and analysi s environment. FUNAP conduct passive monitoring and active probing on the to-be-measured networ k by using(More)
