Abstract
Wireless Sensor Networks (WSNs) have many potential applications. Multi-path routing is widely used in WSN to achieve reliability and perform Fault Tolerance. Multi-path routing determines and assigns multiple routes from a given sensor node to the sink. The transmission of data among the multi-path brings path redundancy, which increases the reliability and reduces the network congestion. In this research work, a dynamic redundancy management algorithm is proposed. To exploit multi-path routing in order to process the user request with existence of defective and malicious nodes. The objective of this work is to analyze the trade-off between energy consumption and Quality of Service (QoS) gain in security and reliability in order to increase the lifetime. The optimized redundancy level of multipath routing is determined dynamically which is used to improve the query response while extending the network lifetime and also for detecting intrusions and send alert to the system through Intrusion Detection System (IDS). Then, a voting-based distributed Intrusion Detection (ID) algorithm is proposed to detect and remove malicious nodes in a sensor network. The malicious node has been determined through number of voters using voting-based distributed ID algorithm. The efficient redundancy management of a clustered Heterogeneous Wireless Sensor Network (HWSN) is to increase the network lifetime in the presence of unreliable and malicious nodes. Therefore, the reliability improved dramatically.
Highlights
Wireless Sensor networks (WSNs) is a network that consist of small, lightweight sensor nodes, distributed in random manner
The Quality of Service (QoS) demands like reliability, timeliness and security are not met in sensor network due to their limited resource availability
Intrusion Detection System (IDS) is used to identity and arrests such malicious nodes. This process leads to rapid consumption of energy which is not reported in previous studies
Summary
Wireless Sensor networks (WSNs) is a network that consist of small, lightweight sensor nodes, distributed in random manner. The vital goal of a WSN is to guarantee the observation of a given area with a restricted number of sensors and transmit the sensed data to the processing unit. In general: a computing subsystem; a communication subsystem short a sensing subsystem; and a power supply subsystem constitute the wireless sensor network. Exchange amid Reliability and energy consumption reported earlier excluded the transfer of malicious node in the network along with packets. Intrusion Detection System (IDS) is used to identity and arrests such malicious nodes. This process leads to rapid consumption of energy which is not reported in previous studies. There are chances of path break due to inside attackers This usually happens in Heterogeneous sensor network. The cluster head actively collects and forwards sensed data to sink node and they are helpful in augmenting the network performance
