WSNs hold the promise of many new applications that require the network to handle traffic with different priority levels and QoS requirement in an energy efficient way while avoiding collisions and interference. In this paper, we investigate several aspects related to the application requirements and the network states and resources in order to provide multi-QoS routing protocol for WSNs. We propose...
This paper presents a new data transmission protocol in Delay Tolerant Mobile Wireless Sensor Networks, which divides the data transmission process into two phases: data reception phase and data forwarding phase, mainly fulfilling through analyzing the state of mobile nodes and using Hand up mechanism. Simulation result shows that, through the implementation of two phases, we can obtain a higher message...
In this paper, a novel routing technology based on circle and wedge trained for wireless sensor networks is proposed to extend network lifetime and to reduce transmission delay. The routing protocol based on hierarchical architecture called CWR protocol need not the routing table, which saves lots of energy and cache of the sensor, also reduces the delay of looking for routing information. To solve...
