Periodical Data collection from unreachable remote terrain and then transmit information to a base station is one of the targeted application of sensor networks. The energy restriction of battery powered sensor nodes is a big challenge for this network as it is difficult or in some cases not feasible to change the power supply of motes. Therefore, in order(More)
Wireless sensor network is a distributed event-based system that differs from traditional communication network. Transporting information in an energy efficient manner Is critical in operating this network for a long period of time. An optimum data dissemination strategy and communication protocols that minimize the use of energy can significantly prolong(More)
This work describes an analysis of ground penetrating radar (GPR) measurements at frequency range of 1.7-2.6 GHz to get a relationship between attenuation and density for nine road pavements slabs with different densities. There are about two different frequencies had been tried. The method is simple, fast, contact less and accurate way to determine the(More)
The Generalized Pareto Distribution (GPD) is used to derive the Intensity-Distribution-Frequency curve for an urban area located in the tropical region using partial duration series (PDS). The Method of L-Moments (LMOM) is used to fit the distribution while the Kolmogorov-Smirnov (K-S) is used for goodness-of-fit test. The procedure was repeated for eleven(More)
