| Research Abstract |
For wireless multihop network, we propose methods on data link layer, which collaborate with network and transport layers. Proposed methods improve throughput and packet loss ratio. In the first method, neighbors of a route, which is determined by network layer protocols, help a node on the route by retransmitting a lost packet. In the second method, data link layer refers information of congenstion control of TCP, and partially disables the backoff procedure of CSMA/CA, to achieve higher throughput and lower packet loss ratio. The last method is a modification of a network layer protocol, OLSR (optimized link state routing). We modify multipoint relay selection algorithm that reduces the number of control packets.
