In order to construct wireless ad hoc networks intended for densely and widely distributed sensors, this research project studies a method of transferring data effectively among those sensor nodes. During two year research period from 2005 to 2006, the following two research topics are studied.1. Selection method of relaying nodes (landmark nodes) for multi-hop data transferIn the environment of high density distribution of sensors, it is possible that many sensors within the radio propagation range increase redundant traffic in the message flooding and data packet relaying. For the purpose of effective flooding and data relaying, this research project proposed a procedure to select landmark nodes which work as relaying nodes for routing control messages and data packets. This research project also showed the performance evaluation of the proposed procedure with the comparison to OLSR (Optimized Link State Routing), which is being standardized in IETF for high density ad hoc networks. This project used a software simulation technique and evaluated the number of selected relaying nodes and the number of flooded messages for routing information exchange. The results showed that the proposed procedure could reduce both of them compared with OLSR.2. Ad hoc routing suitable for high density ad hoc networksThis research project also proposed a modified version of AODV (Ad hoc On-demand Distance Vector) routing protocol adapted to high density ad hoc networks. It has features such that it does not introduce any additional message overhead, that it makes only the required nodes relay route request messages and that it copes with network configuration change. This research project showed the performance evaluation using a network simulator. The results indicate that the proposed protocol can reduce the total number of control messages and that data packet loss due to the control message overhead is reduced compared with the original AODV.

为了构建用于密集和广泛分布的传感器的无线临时网络，该研究项目研究了一种有效传输数据之间的数据的方法。在2005年至2006年的两年研究期间，研究了以下两个研究主题1。用于多跳数据传递传感器的高密度分布环境中的传递节点（地标节点）的选择方法，无线电传播范围内的许多传感器可能会增加消息洪水泛滥和数据包中继的冗余流量。为了有效的洪水和数据继电器，该研究项目提出了一个程序，以选择具有路由控制消息和数据包的传递节点的地标节点。该研究项目还显示了对拟议程序的性能评估与与OLSR的比较（优化的链路路由），该程序在IETF中对高密度临时网络进行了标准化。该项目使用了软件仿真技术，并评估了所选继电器节点的数量以及用于路由信息交换的洪水量的数量。结果表明，与Olsr.2相比，提出的程序可以减少两者。适用于高密度临时网络的临时路由该研究项目还提出了AODV（临时按需距离矢量）路由协议的修改版本，适用于高密度临时网络。它具有使得它不引入任何其他消息开销的功能，它仅使所需的节点中继路由请求消息并与网络配置更改相抵抗。该研究项目显示了使用网络模拟器进行绩效评估。结果表明，所提出的协议可以减少控制消息的总数，并且与原始AODV相比，由于控制消息开销而引起的数据包丢失会减少。
