A study of multi-hop mobile communication access models considering elapsed time from coverage area

In this paper, we focus on multi-hop mobile communication. We propose a mobile communication model that able to connect to base-station by using multi-hop, when some nodes are in the outside of the coverage area of basestations. At first, we examine the "AODV model" considered AODV (ad hoc on-demand distance vector routing) already proposed as routing algorithm in ad-hoc network. When using AODV model simulation, we get a result that the coverage area of base-station is expanding. However, this model has some problems with a gain of node density such as a packet collision, an increase of relay node and a lode on the channel. Therefore, we propose a new model to improve the AODV model, and we compare performance of proposed model with the AODV one. We also show that our proposed model has an improvement compared to the AODV model.
