We introduced the localization algorithm to find the coordinates of nodes in WSN. The proposed algorithm starts at measuring the angle and distance at the landmark and their neighbors and then finding their azimuths and incident angles. In this paper, four kinds of the method to calculate and update the coordinates of nodes are proposed. The simulation results show that to utilize more data obtained...
Most of the MAC and routing protocols proposed for wireless ad hoc networks are based on omni-directional antenna. Omni-directional antenna distributes energy in all directions, not only causing unnecessary interference to other nodes, but also reducing the potential range of the transmission. In this paper, we propose a novel medium access control and routing protocols for wireless ad hoc networks...
Among the research community, on-going efforts are being continued to efficiently interconnect MANETs to fixed infrastructure in order to expand the reach of the Internet to Wireless access networks. Such scenario gives raise to a number of challenges that require solutions involving Internet gateway selection scheme, extensions to ad hoc routing technique. In this paper, we depict a network architecture...
