In a 1-D linear vehicular ad hoc network (1-DL-VANET), some vehicles may leave the network (e.g., at highway exits), which may make the 1-DL-VANET disconnected. Thus, it is important to analyze the connectivity of the 1-DL-VANET. When removal of any arbitrary nodes from a network does not disconnect the network, the network is said to be -connected. In this paper, we investigate the...
Mobility of nodes is considered as the potential solution for improving Ad Hoc network performance, such as maintaining a specified network topology, improving the power efficiency, and enhancing signal-to-noise ratio at the receivers, etc. However, node movement consumes certain amount of energy, which is limited at nodes, and should be counted when optimizing the system performance. In this paper,...
In wireless ad hoc networks, in order to prolong network life time and improve network capacity, it is necessary to reduce large transmission power of nodes. Due to the random distribution of nodes, traditional topology control algorithms fail to solve this problem completely. So we propose a distributed movement control algorithm to solve this problem. Target locations and redundant nodes are identified...
