An examination of existing studies in the area of Routing Protocol for Low-Power and Lossy Networks (RPL) implementation in wireless sensor networks (WSNs) reveals a consistent approach taken of optimal node distribution. This in order to best evaluate networking metrics such as Packet Delivery Ratio (PDR), latency and energy consumption. The tests detailed in this paper differ from previous work,...
Wireless Sensor technology is one among the fast emerging technologies in the current scenario and it has wide range of application also which has small sensors with minimum communicational and computational power. Depending on the overhead of a node, the energy consumption varies with each other. This leads to the non-uniform distribution of the energy which in turn degrades the performance of the...
The security routing protocols practiced in a wireless sensor network are not enough to thwart the potential security breaches in heterogeneous wireless sensor networks. After reviewing the existing research methodologies to resist the adversaries, it was found that existing techniques are either computationally expensive process or lead to communication overhead.

Wireless Sensor Networks (WSNs) are often deployed in remote and hostile areas and because of their limited power and vulnerability, the sensors may stop functioning after sometime leading to the appearance of holes in a network. A hole created by the non-functioning sensors in turn severs the connection between one side and the other side of the network and alternative routes need to be found for...
The contribution of this article is two local recovery methods that may reduce overhead and make a more immediate reconnection of disconnected nodes compared to the soft state global recovery method applied in WSNs running RPL [1]. In addition, we perform an analysis of the implication to better judge the context where local recovery methods should be used. One of our suggested methods is based on...
