| Abstract(in English) | In wireless sensor network WSN, data are collected and transmitted toward one node called a sink, if necessary, in a multi-hop fashion. The nearby node to sink is always forced to transmit data more often and therefore possibly earlier dries out energy in WSN. Such situation is known as a hot spot problem. Mobile sink is one solution of such problem. That is, if a sink moves, then hot spots also move and resultantly distribute the load, which is expected longer lifetime of WSN. Recently, we have assumed that sink moves along the boundary of WSN with grid structure because theoretical approach seems easy to tackle for that structure. There, we consider the difference between transmission trees among different sinks. Then we define stable transmission trees for such sink movement in one round that change to a minimum. As a result, we have developed an algorithm to obtain such trees. On the other hand, for a fixed sink, by restricting the shortest-path tree structure for transmission, we easily apply the problem of a transmission tree with desirable node cost to linear programming. This report considers three relevant problems and discuss the difference between those two transmission trees obtained above mainly in viewpoint of longer lifetime of WSN. |
