An adaptive cost function for routing protocols in wireless networks

Routing protocols have been widely used in wired networks. In wireless environment, however, cost function of the protocol needs to be modified. We propose a new cost function for routing protocol which considers the unstable condition of wireless links: Using BER (Bit Error Rate) of a link, a channel capacity is calculated and is called effective bandwidth. Performance analysis using simulation shows that our cost function can achieve better performances than original one.
