TRANSMISSION POWER CONTROL IN WIRELESS SENSOR NETWORKS UNDER THE MINIMUM CONNECTED AVERAGE NODE DEGREE CONSTRAINT

As a branch of topology control, power control is of great importance to prolong the survival time of the network. A transmission power control algorithm is proposed under the minimum connected average node degree constraint in this paper. Using a Poisson point process in two dimensions, we derive an analytical expression that determines the required transmission range to achieve a specified connectivity probability for a given node density, and then the minimum connected average node degree is

FINDING THE SHORTEST PATHS AMONG CITIES IN JAVA ISLAND USING NODE COMBINATION BASED ON DIJKSTRA ALGORITHM

This study focuses on finding the shortest paths among cities in Java Island by repeatedly combining the start node’s nearest neighbor to implement Dijkstra algorithm. Node combination is used to find the shortest path among cities in Java by deleting the node nearest to the start node. The use of memory by node combination is more efficient than the use of memory by the original Disjkstra algorithm. The 46 cities in Java Island will be used to evaluate the performance of finding shortest path
