WSN nodes resource constrained. In order to keep the size and the cost of the nodes down, the nodes have limited processing power, memory and radio range. However, the resource constraint which has the most significant impact on many WSNs is the constraint on energy. WSN nodes are battery operated. Many wireless sensor networks are deployed in locations where battery replacement is not feasible. A node has to be discarded when the battery depletes. Energy scavenging may alleviate this problem in some sensor networks. Most WSN protocols are very conscious of the limited supply of energy, and try to conserve energy.
Mobile applications are the current money spinning idea in the field of technology. It is system software that runs on android and smartphones. Many researchers use app developing technologies to write thesis. Thesis on this technique is very useful as it gives a detail account on the characteristics of mobile application is software built by the mobile development software for accessing handheld devices like laptop, mobile phones and enterprise digital assistance etc. Mobile application technology is an integral part of the human everyday life. Mobile application thesis topics can be based on developing upnp (Universal plug and play), mobile infected virus, WBAN (Wireless Body area Network), GPS tracking, LTE, 5G networks, social sensor network, mobile banking etc.
