“…In recent years, many limitations of WSNs, including cost, limited processing and computing resources, and shorter battery life have been improved significantly [1]. As a result, a wide range of tiny sensors-mechanical, thermal, biological, chemical, optical and magnetic sensors-is being designed to perform various tasks [2].…”

Since wireless sensor networks (WSNs) have been designed to be deployed in an unsecured, public environment, secured communication is really vital for their wide-spread use. Among all of the communication protocols developed for WSN, the Security Protocols for Sensor Networks (SPINS) is exceptional, as it has been designed with security as a goal. SPINS is composed of two building blocks: Secure Network Encryption Protocol (SNEP) and the "micro" version of the Timed Efficient Streaming Loss-tolerant Authentication (TESLA), named µTESLA. From the inception of SPINS, a number of efforts have been made to validate its security properties. In this paper, we have validated the security properties of SNEP by using an automated security protocol validation tool, named AVISPA. Using the protocol specification language, HLPSL, we model two combined scenarios-node to node key agreement and counter exchange protocols-followed by data transmission. Next, we validate the security properties of these combined protocols, using different AVISPA back-ends. AVISPA reports the models we have developed free from attacks. However, by analyzing the key distribution sub-protocol, we find one threat of a potential DoS attack that we have demonstrated by modeling in AVISPA. Finally, we propose a modification, and AVISPA reports this modified version free from the potential DoS attack.

Abstract-As wireless sensor networks are energy constraint networks so energy efficiency of sensor nodes is the main design issue. Clustering of nodes is an energy efficient approach. It prolongs the lifetime of wireless sensor networks by avoiding long distance communication. Clustering algorithms operate in rounds. Performance of clustering algorithm depends upon the round time. A large round time consumes more energy of cluster heads while a small round time causes frequent re-clustering. So existing clustering algorithms apply a trade off to round time and calculate it from the initial parameters of networks. But it is not appropriate to use initial parameters based round time value throughout the network lifetime because wireless sensor networks are dynamic in nature (nodes can be added to the network or some nodes go out of energy). In this paper a variable round time approach is proposed that calculates round time depending upon the number of active nodes remaining in the field. The proposed approach makes the clustering algorithm adaptive to network dynamics. For simulation the approach is implemented with LEACH in NS-2 and the results show that there is 6% increase in network lifetime, 7% increase in 50% node death time and 5% improvement over the data units gathered at the base station.

“…Wireless sensor network consists of several sensor nodes that collect data in inaccessible areas and send them to the BS after initial processing [1]. Nowadays, with respect to the increasing number of applications such as: environmental, medical, military, industrial applications, etc, designing efficient security mechanisms considering the type of the applications is obviously needed.…”

Abstract-Nowadays with the wide range of applications in wireless sensor networks, there is an increasing need for security of these networks. These networks have been subjected to numerous attacks among which Sinkhole attack is one of the notable ones. In Sinkhole attack, sometimes the adversary node poses itself as a fake base station (BS) and receives all data of the network. It prevents data from reaching the main BS, or changes the received data and then transfers them to the main BS. In this paper, we present an efficient algorithm in terms of energy consumption. In the proposed algorithm, when a node desires to send data to the BS, it firstly sends a control packet directly to the main BS. Then it begins to send data packets to the BS in form of hop by hop routing. When the data packet arrives at the BS, some of its control fields are compared with the same ones of the original control packet. If any changes have been made to these control fields of the data packet, it shows that there is a malicious node; the BS detects it using the proposed strategy. The performance of the proposed method has been evaluated and compared with that of Ngai's algorithm. The simulation results indicate that the proposed algorithm is more efficient than it.Index Terms-Wireless sensor networks, sinkhole attack, wormhole, base station, detection.
