WSN nodes operate in an unattended environment and thus have irreplaceable batteries. Thus an important concern is the network lifetime; we need to utilize their energy for a longer time otherwise nodes run out of power. For this purpose various protocols have been established and the subject of our matter is the LEACH protocol. The LEACH protocol is self-organizing and is characterized as an adaptive...
Hello flood attack has long been a problem in ad-hoc and wireless networks during data routing. Although numerous solutions have been proposed, they all have drawbacks. The main reason is that formal modeling techniques have not been employed to confirm whether the solutions are immune from DoS attacks. We have earlier shown how formal modeling can be utilized efficiently to detect the vulnerabilities...
Sensor networks are low power and low cost embedded system they have limitations like speed and memory. Most sensor networks communicate wirelessly and have variety of applications. One application of sensor networks is discussed in this paper which is to sense temperature remotely. It was observed after computer simulations that the base station was not able to receive temperature data of all nodes...
