Network coding is a novel technique to improve network throughput and performance by efficient encoding over the intermediate nodes in the network and works particularly well in multicasting. We expect that network coding will reduce the bandwidth utilization of IP broadcasting services that provide multichannel services and high quality videos using IP multicast. However, it is difficult to apply...
Energy consumption is not well balanced for all sensor nodes in most of the energy efficient routing protocols for wireless sensor networks (WSNs). In this paper, we optimize each individual distance so that all sensor nodes consume their energy at similar rate. After the theoretically analysis of hotspot based on certain energy and traffic models, we propose our Distance-based Energy Aware Routing...
In this paper, we propose a new dynamic energy efficient routing scheme for wireless sensor networks. Based on the dynamic reconfiguration approach, the proposed scheme can provide network adaptability while enhancing the network efficiency. In addition, our distributed control paradigm has low complexity, making it practical for real sensor network management. Simulation results indicate the superior...
This paper presents a reservation based reliability control protocol for wireless sensor networks having the applications that demand in-order and 100% delivery of the generated packets. Unlike earlier works the proposed reliability control avoids channel contention and collision problem during retransmission, and ensures guaranteed packet delivery. Moreover, the reservation based retransmission can...
To operate e-mail systems stably multihomed networks are well used. As an operation method on multihomed networks, we have proposed a dynamic route selection method considering status of networks. However, status of Mail Transfer Agents(MTAs) have not been considered in this method so that a heavily loaded MTA would be possibly selected. In this paper, we propose a new dynamic route selection method...
