Design and performance assessment of energy aware security enhancing strategy for PEGASIS protocol for MWSN

Abstract

Due to wide variety of applications, Wireless Sensor Networks have been extensively used and many researchers are engaged in research in this area including Mobile Wireless Sensor Networks (MWSN). The major issues in use of MWSN however are energy consumption, security, scalability, robustness etc.. It is generally observed that clustered WSN networks using hierarchical routing protocols, significantly reduce the overall energy consumed. However, some of these protocols do not address the security issues related to different attacks. A security enhanced Sec-LEACH protocol results in higher security using random key predistribution and TESLA.In this paper, an approach has been implemented to arrive at an energy aware security enhancing strategy for Power-Efficient GAthering in Sensor Information Systems (PEGASIS) and referred to as Sec-PEGASIS protocol. The performance evaluations have been done for three important metrics namely residual energy, packet delivery ratio and routing overheads. The performance comparison has been done with respect to LEACH, Sec-LEACH and normal PEGASIS protocol for different rounds of data collection. It is seen that energy aware security enhancing strategy proposed in this paper provides higher level of security, retaining the energy efficiency feature of PEGASIS protocol unaltered.

Design and Analysis of a Data Fusion Scheme in Mobile Wireless Sensor Networks Based on Multi-Protocol Mobile Agents

“…Communication energy consumption accounts for a large part of the energy consumption of the entire sensor network due to the large amount of multimedia information. The MWSN has multi-level, multi sink, distributed sensor nodes of a variety of network systems [ 26 ]. Moreover, it is necessary to classify monitoring data from different nodes, all of which need many data transfers.…”

Cross layers security approach via an implementation of data privacy and by authentication mechanism for mobile WSNs

“…Thus, several authors go to the security of the routing path. Such as SecLEACH and SecPEGASIS protocols, which present the first solutions for securing hierarchical (cluster-based) networks with the dynamic clusters formation [15][16], also inwork [17] authors present a cross layers routing protocol. With the aim of providing an acceptable level of security, other researchers have developed either protocols assuring data confidentiality, such as DiDrip algorithm [18], techniques guaranteeing authentication and data integrity [19], or techniques providing secure data aggregation [20].Another research line turns to the cryptography aspects.…”
