A Group-Based Data Transmission Algorithm in Delay Tolerant Sensor Networks

Free registration required

Executive Summary

This paper proposes an efficient data delivery algorithm called Group-based Data Transmission (GDT) for Delay Tolerant Mobile Sensor Networks (DTMSN). In GDT, the authors introduce the principle of node's "Group exercise" behavioral characteristics in data transmission in order to deal with the problem of mobility model used in delay tolerant sensor network, and then lead to improved data delivery performance. In GDT, Inter-Group delivery will be achieved by multi-replica delivery based on its delivery probability that the node meets the sink, and Intra-Group delivery will be performed by single-replica delivery through established transmission path.
