LAP Lambert Academic Publishing This book gives an excellent overview on secure and energy efficient data collection taking sink as the dynamic and other sensors are static in Wireless Sensor Networks. Mobile sink wireless sensor networks (MSWSN) Sensor nodes are low cost tiny devices with limited storage, computational capability and power except the sink node. Mobile sink has no resource limitation. Here we proposed energy efficient secure data collection techniques with mobile sink wireless sensor networks and secure the data collection process using symmetric key cryptography. we also proved an existing protocol Sensor Protocol for Information via Negation (SPIN) is efficient for critical data transmission to the mobile sink. Then we make it as the secured protocol by using symmetric key cryptography. All the simulation has been carried out with NS 2.34. This work is supported by the literature survey in the area of Mobile Sink Wireless Sensor Networks to make it complete.
