| dc.description.abstract | Mobile ad-hoc network (MANET) is a decentralized wireless network composed of dozens to hundreds of nodes. Without those pro-existing networking infrastructures, MANET transmits messages through dynamic routing methods, which succeeds in data delivery between source and destination nodes. However, there are some disadvantages such as limited network bandwidth, poor support for real-time services, and low security. This study aims to reduce the cost of message transmission and increase the delivery rate.Thus, we proposes a message transmission scheme based on the nodes′ movement trend and geographic location to select a two-hop route for MANET, named Routing Scheme Based on Node Mobiility and Geographic Location (RSMG). Firstly, we use the connection between the current node and the destination as the baseline, limit the scanning range, and obtain the one-hop nodes within the range. Secondly, we take this information as the basis and scan the next-hop nodes to filter all paths, then obtain candidate paths. Thirdly, we calculate the offset angle according to the velocity vector, then calculate and assign a weight value for all paths. Finally, we filter all paths according to the weight value for data transmission.We take the delivery rate and cost as performance indicators. The results showed that our solution was 10% lower than the Epidemic delivery rate, but the cost was reduced by 90%; compared with the other two schemes, Our solution has a lower cost when the delivery rate is 10% to 20% higher. | en_US |
