In this paper, we firstly propose a maximum lifetime routing: the path cumulative power consumption routing(PCPC), based on the information of the two layers: medium access and routing. Secondly, a min-max optimal programming model is presented to describe the routing strategy. It aims to maximize the sensor network lifetime with minimal network power consumption by exploiting the cross-layer optimization...
Delay tolerant networks (DTNs) experience frequent and long lasting network disconnection due to various reasons such as mobility, power management, and scheduling. One primary concern in DTNs is to route messages to keep the end-to-end delivery delay as low as possible. In this paper, we study the single-copy message routing problem and propose an optimal opportunistic routing strategy – Leapfrog...
The performance of AODV protocol of MANET at the rate of 4G is studied. A network frame is introduced, the network model is set up, and simulations are run in NS2. After analysis the results show that AODV is suitable for the network of low moving speed at the rate of 4G, but not suitable for the network with too high speed. The work has some value in the integration of MANETs and 4G mobile communication...
