The energy consumed by topology maintenance could be higher than that in the initialization stage and the cost will increase steadily with the turns of maintenance process. Therefore, when design a self-organization protocol for WSN, not only initialization cost should be considered but also the maintenance cost in the whole lifetime. Moreover, to reduce the footprint on system resource, the maintenance...
Energy efficiency is a key problem of wireless sensor networks. Though we already have many self-organization protocols which can build energy-saving structures, the energy cost of maintenance also must be concerned. We found that organized network structure has great impact on the energy cost in the maintenance stage and the overall energy efficiency. In this paper, we classify the self-organization...
An important feature of the difference between wireless sensor networks and traditional wireless networks is that energy of sensor node is limited. Therefore, how to design energy efficient sensor network system has been the focus of the study in related fields. Now there are many self-organization protocols in wireless sensor networks, but most only take the initial energy consumption into account...
Network reprogramming is a crucial service in wireless sensor networks (WSNs) that relies on epidemic strategy for spreading software updates by just having a local view of the networks. Securing the process of network reprogramming is essential in some certain WSNs applications, state-of-the-art secure network reprogramming protocols for WSNs aim for the efficient source authentication and integrity...
With highly dynamic, structured P2P system needs very large maintenance cost. But there is little research on this kind of maintenance. This article focuses on reducing maintenance cost of structured P2P system and proposes a clone node protocol, CNP for short. We realize a new system based on vxusing CNP, i.e. CNChord. CNP can reduce maintenance cost greatly, and improve query efficiency at some...
