Abstract

A method is proposed for bandwidth table constructions in synchronized QoS ad hoc networking. In this scheme of networking, specified bandwidth is reserved for each communication path based on bandwidth tables constructed by each terminal. This bandwidth reservation is desirable in diaster areas where rescue teams need to share wideband picture images of distant locations sent from rescue robots or human scouts. However, because process gain of associated CDMA operation is assumed to be high enough, unreasonable ra-diowave bandwidth is necessary for the system designs. The proposed method for bandwidth table construction regards CDMA interferences when the process gain is set arbitrary. With this method, system designs with reasonable radiowave bandwidth become possible. Simulations confirm the network performances with the proposed method.
