Two important criteria of wireless body area networks (WBANs) are low power consumption and delay. These can be met by designing efficient medium access control (MAC) protocols. In this paper, two TDMA-based MAC protocols proposed. The first protocol, TM–MAC makes use only a main radio. second proposed TWM–MAC WUR alongside the compared with different categories standard it is shown that they o...

soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.so, this research has been done for achieving this purpose. this area is arounding sa...

Wireless Sensor Networks (WSNs) comprising of tiny, power-constrained nodes are getting very popular due to their potential uses in wide applications like monitoring of environmental conditions, various military and civilian applications. The critical issue in the node is energy consumption since it is operated using battery, therefore its lifetime should be maximized for effective utilization ...
