SALR: Secure adaptive load-balancing routing in service oriented wireless sensor networks
(2015) Lata, B.T.; Sumukha, T.V.; Suhas, H.; Tejaswi, V.; Shaila, K.; Venugopal, K.R.; Anvekar, D.; Patnaik, L.M.
Congestion control and secure data transfer are the major factors that enhance the efficiency of Service Oriented Wireless Sensor Networks. It is desirable to modify the routing and security schemes adaptively in order to respond effectively to the rapidly changing Network State. Adding more complexities to the routing and security schemes increases the end-to-end delay which is not acceptable in Service Oriented WSNs which are mostly in real time. We propose an algorithm Secure Adaptive Load-Balancing Routing (SALR) protocol, in which the routing decision is taken at every hop considering the unforeseen changes in the network. Multipath selection based on Node Strength is done at every hop to decide the most secure and least congested route. The system predicts the best route rather than running the congestion detection and security schemes repeatedly. Simulation results show that security and latency performance is better than reported protocols. � 2015 IEEE.

SGR: Secure geographical routing in Wireless Sensor Networks
(2015) Lata, B.T.; Tejaswi, V.; Shaila, K.; Raghavendra, M.; Venugopal, K.R.; Iyengar, S.S.; Patnaik, L.M.
Geographical Routing Technique is a new trend in Wireless Sensor Networks in which the sensor nodes are enabled using Global Positioning Systems(GPS). This helps to easily detect the position of their neighboring nodes. The power consumption is more in the existing routing algorithms, since the nodes build the routing tables and the neighboring node IDs are determined by searching the routing table. In this paper, we have proposed Secure Geographical Routing (SGR) algorithm in which the data traffic and energy consumption is minimized using single copy data transfer. In SGR, initially one copy is transmitted to the next node using greedy approach and another copy is preserved in the sending station. If acknowledgment is not received even after timeout then the second copy is transmitted. This dynamic single copy scheme reduces the data traffic in Wireless Sensor Networks. Security algorithms are incorporated in every sensor node to prevent any malicious node attack that disturb the normal functioning of the network. Simulation result shows that the performance of the proposed algorithm is better in terms of packet delivery probability and energy consumption in comparison with existing algorithms. � 2014 IEEE.
