In this paper, we employ the centering theory in pronoun resolution from the semantic perspective. First, diverse semantic role features with regard to different predicates in a sentence are explored. Moreover, given ...

Almost all proposed routing protocols are based on minimum hops in mobile ad hoc network. But through the research on the real communication of wireless nodes, we find that sometimes the path which has the minimum hops from the source to the destination may not be the best path. Considered the remaining power and the node selfishness, we propose an improved AODV routing protocol, I-AODV in this paper. We use a new term, node status, regard the node status as a function of the remaining power and the fame and regard the node status as the basic condition for choosing the next hop in the new routing protocol.
