Designing Path Assured Data Transfer Protocol for Wireless Sensor Network (original) (raw)

2013, International journal of engineering research and technology

wireless sensor networks is a growing class of highly dynamic, complex network environment on top of which a wide range of applications, such as habitat monitoring, object tracking, precision agriculture, building monitoring and military systems are built. The real time applications often generate urgent data and one-time event notifications that need to be communicated reliably. The successful delivery of such information has a direct effect on the overall performance of the system. Reliable communication is important for sensor networks. The traditional transport layer protocols in WSN are not directly useful to meet this requirement. There is a need to synthesize the WSN characteristics and transport layer requirement for the same. Motivated by these challenges, we propose an autonomous and distributed mechanism, called as "Path Assured data Transfer" (PAT) mechanism for fast and reliable transmission for urgent information in WSNs.
