Wireless Sensor Networks (WSNs) have ample applications in a wide range of domains such as health care monitoring, environmental, critical infrastructure, and military applications. These extensive usages of WSNs make them an attractive target for all adversary attacks and natural risks. Although there exist solutions against these threatening attacks, they(More)
Wireless Sensor Networks (WSN) are used in various critical monitoring applications such as military safety, environmental surveillance, etc. In such scenarios, it is common that WSN nodes are threatened by potential adversaries. Since the network lifetime is known to be the one of the most important performance metrics in WSNs, capturing the most critical(More)
Extraction and integration of entities from textual data and linking them to knowledgebases (for further information or processing) is useful for many applications in natural language processing. However, a major problem in this process is disambiguation, named entities might refer to different things. In this work, we propose a novel method to disambiguate(More)
Extension of network lifetime and reduction of latency are two of the most challenging topics in Wireless Sensor Networks (WSNs). This work presents a novel approach utilizing of Mixed Integer Programming (MIP) optimization. We explain how such an approach is made viable for WSNs via new wireless software defined network (WSDN) architectures and protocols.(More)
