BMSTU Master's thesis. Energy efficient wireless sensor network routing protocol with hierarchical clustering based on the genetic algorithm. Wireless Sensor Network 1. Introduction A Campbell Scientific Wireless Sensor Network consists of a CWB100 Wireless Base Station which uses RF to communicate with one or more wireless sensors. The base station serves as the gateway to the network, communicating with a Campbell Scientific CR800-series, CR1000, or CR3000 Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Most of the attention, however, has been given to the routing protocols since they might differ depending on the application and network architecture. Industrial Wireless Sensor Networks: Applications, Protocols, and Standards examines the current state of the art in industrial wireless sensor networks and outlines future directions for research. What Are the Main Challenges in Developing IWSN Systems?

Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor net-works where energy awareness is an essential consideration. Most of the attention, however, has been given to the routing protocols since they might differ depending on the application and network architecture. This paper surveys Key Establishment Protocol for Wireless Sensor Networks 171 2.1 Key establishment protocols b ased on random key pre-distribution Eschenauer et al. [Eschenauer & Gligor, 2002] proposed a random key pre-distribution scheme for WSNs. In this approach, before deployment some keys from a large key pool are selected randomly and stored in the sensors. Learn all you need to know about wireless sensor networks!

WSN is a wireless network that consists of base stations and numbers of nodes (wireless sensors).These networks are used to monitor physical or environmental conditions like sound, pressure, temperature and co-operatively pass data through the network to a main location as shown in the figure. Wireless sensor networks may be considered a subset of Mobile Ad-hoc NETworks (MANET). WSN nodes have less power, computation and communication compared to MANET nodes. MANETs have high degree of mobility, while sensor networks are mostly stationary. Freq. node failures in WSN -> topology changes

Thousands to millions of small sensors form self-organizing wireless networks. Security for these sensor networks is not easy since these sensors have limited processing power, storage, bandwidth, and energy. A set of Security Protocols for Sensor Networks, SPINS, explores the challenges for security in sensor networks. SPINS include μTESLA (the micro version of the Timed, Efficient
