Implementation of Square-Odd Scanning Technique in WBAN for Energy Conservation

The increasing population needs large medical staff for the excellent healthcare services. By the introduction of wireless sensor networks in the field of medical world, we hereby solve the problem of shortage of medical staff across the world. The WBAN gives an excellent opportunity to improve the quality of medical healthcare system. Establishing a wireless network in the field of medical is a very difficult issue as the protocol used for the adhoc network doesn’t perform efficiently in the mobile WBAN. This needs a scanning policy for the WBAN to be added in routing to improve the network lifetime and to reduce the errors of the existing protocols for WBAN. The nodes of the sensor network remains active at all times whereas the utilization period of the sensor nodes is only 20% of the total time. This results in high energy consumption. This results in need of an efficient scanning technique for WBAN with dynamic active period. Wireless sensing network uses very light sensors which have very low power backup. So power saving is very important in such type of network. Square-Odd scanning is used to save significant power in wireless sensors. It periodically switches the sensors between sleeping and awake mode. Square-Odd scanning is an improved method for scan the object with increase network lifetime. It focuses on reduction in energy consumption and it improves the life time of sensor. The performance of the Square-Odd approach is better than all other previous scanning algorithms in terms of network lifetime. In this paper we describe existing scanning techniques and proposed scanning algorithm for power saving in WBAN.
