A Security Architecture for Mobile Wireless Sensor Networks

Abstract

Abstract. Wireless sensor networks increasingly become viable solutions to many challenging problems and will successively be deployed in many areas in the future. However, deploying new technology without security in mind has often proved to be unreasonably dangerous. We propose a security architecture for self-organizing mobile wireless sensor networks that prevents many attacks these networks are exposed to. Furthermore, it limits the security impact of some attacks that cannot be prevented. We analyse our security architecure and show that it provides the desired security aspects while still being a lightweight solution and thus being applicable for self-organizing mobile wireless sensor networks.

A Survey on Wireless Sensor Networks Security with the Integration of Clustering and Keying Techniques

“…The position of sensor nodes need not be engineered or pre-determined [15]. The sensor network protocols and algorithms must possess self-organizing capabilities [13]. Instead of send-ing the raw data to the nodes responsible for the fusion, sensor nodes use their pro-cessing abilities to locally carry out simple computations and transmit only the required and partially processed data [17] and this technique is known as 'data aggregation'.…”

“…The most common form of WSN topology consists of the a collection of a large number of sensor nodes and a Base Station (BS). Each sensor nodes are constrained by limited battery power, small memory, low computational ability and limited transmission range [13]. On the other hand the BS has larger memory and processing power.…”

“…Security is another important issue of WSNs [13]. Since the sensor networks are usually deployed in uncontrollable environments that are not trustworthy, thus WSN is exposed to the common security threats like information disclosure, message injection, and replay attacks etc.…”

Wireless Sensor Networks - Architecture, Security Requirements, Security Threats and its Countermeasures

“…The common security threats include information disclosure, message injection, sleep deprivation attack etc [5]. An attacker may capture and compromise a node and thus be able to control some part or even the whole network exclusively [5].…”

“…The common security threats include information disclosure, message injection, sleep deprivation attack etc [5]. An attacker may capture and compromise a node and thus be able to control some part or even the whole network exclusively [5]. For example, in a sleep deprivation attack the intruder makes a node or a set of nodes to remain busy; so that they waste their energy while carrying out the task for the intruders [6].…”
