Improved Efficiency and Increased Lifetime In WBAN Using Hybrid Mac Protocol and DCD Algorithm

Abstract

Wireless Body Area Network (WBAN), a wireless network with numerous of small intelligent devices like Sensors, Actuators, PDA that are connected in the garments, on the human body rounder the skin of the person. Which is eligible of transferring data through the wireless medium and other topology of the network is based on the placement of nodes in the human body. The main aim of WBAN is to increase health care and quality of life. Applications of WBAN has human health care monitor like hospital/home/other places such as sports, home automation like poison/gas detection, consumer electronics like MP3 player, head mounted devices, games. In this we design an efficient and reliable transmission path for data flow from source to sink node near to the destination. Using this technique we have to improve the output performance and life cycle of the each node in network. The BAN is a main source for wireless communication in the field of medical electronics. It uses various resources such as channel, frequency, bandwidth etc. To make the communication faster and easier. Hence the data losses and delay are the main issues in the BAN, to address these issues many protocol and algorithm are proposed the issues are not completely addressed yet. Implementing line equation and frequency splitting algorithm and this algorithm is used to calculating distance between the nodes. BAN allows to utilize unused spectrum so we have to check that channel using channel estimation techniques. After channel estimation we can measured frequency range and bandwidth of that channel. In this system we are implemented best frequency generator or clock generator for generate various frequency based on the nodes distances. In our system we use the optimal methodology to address these problem, we obtain the maximum efficiency through our proposed system. Source and destination first then the channel, bandwidth and frequency will be allocated as per the distance. If the distance increases the resources also increased and vice versa.
