- Abstract
- Achieving efficient data dissemination to a mobile sink moving is one of the main challenges in wireless sensor networks. In this paper, we describe DHA, a data Dissemination protocol based on Home agent and Access node. DHA introduces the home agent and access node concepts to represent the mobile sink in sensor networks. The movement of the mobile sink affects only the access nodes and home agent, and the sensor nodes can transfer data to the fixed home agent without knowing the position of mobile sink. All the sensor nodes except the home agent and access node don't need to be updated in the direction of forwarding future data. DHA provides reliable and efficient data delivery to a mobile sink with minimum overheads. Our result shows that DHA increases the reliability of data delivery to the mobile sink and reduces the number of broadcast packets, thereby increasing the lifetime of sensor networks. © 2011 Springer-Verlag.
