In wireless sensor networks, ??holes?? are hardly to know its location and avoid either because of various actual geographical environments. A hole can be dynamically formed due to unbalanced deployment, failure or power exhaustion of sensors, animus interference, or physical barriers such as buildings or mountains. Hence, we hope to propose the RNG Hole Avoiding Routing protocol, RNGHAR which can...
Wireless sensor networks (WSNs) is composed of sink and many sensor nodes. It has the great scope to monitor environment and the characteristics of wireless communications. Relatively, the advantages of sensor node bring themselves some restrictions. The greatest challenge among those is the constraints on energy. The most critical issue is how to minimize the energy consumption for keeping target...
Hierarchical Mobile IPv6 management(HMIPv6) which is drawn up by the IETF (Internet Engineering Task Force) utilizes the Mobile Anchor Point (MAP) to reduce the considerable number of binding update messages among the mobile node, correspondent node, and the mobile node's home agent. According to the HMIPv6 mechanism, the MAP of higher layer can efficiently reduce the frequency of binding update messages;...
