Wireless Sensor Networks (WSNs) have received academia research attention at present. The energy-constrain sensors in wireless sensor networks operate on limited batteries, so it is a very important issue to use energy efficiently and reduce power consumption. Most recent routing protocols tend to find the minimum energy cost path to lower energy usage for all routing paths, thus, they may lead to...
This paper proposes a dynamic geographic hash table for data-centric storage (DCS) in sensor networks. In DCS systems, data storage locations are determined by data name. The storage locations are obtained through the use of a geographic hash table (GHT) that maps data names to geographic locations. Traditional DCS systems use a static hash function for this purpose, resulting in a static set of nodes...
