A Review of Delay Tolerant Protocol for Data Aggregation in WBAN Application

Wireless Body Area Network is an essential part of IOT (internet of thing) which benefits in gathering data from the body surface area. The wireless body area network is the type of network in which sensor devices can sense the body conditions and pass to base station. It has number of applications for health monitoring. To maintain the quality of dissemination of the observed data, data aggregation techniques are immensely used. The foremost aim of data aggregation method is to assemble and cluster data packets in a well-organized and cos-effective way so as to minimize power consumption, to intensify network life time, delay, traffic congestion etc. In wireless body area network data aggregation with high delay tolerance is of utmost importance. In WBAN, delay tolerant network means in the network data storage node is formed which is used to the information transmission. This paper work is based on the study of different data aggregation methods and delay tolerant network to reduce delay in the network.
