“…In addition, to improved bandwidth, range, interference, power efficiency and security at the physical layer, we demonstrate the feasibility for practical networklevel routing and the security advantages against networklevel routing attacks through analysis of average hop count, localization error and the risk of insider attack. Additional performance and security analysis by the authors can be found in [22], [25], [36], [33], [12].…”

“…For example, in a three node insider link scenario, if s b → s c , s b → s a and s c → s a all exist, then a potentially corrupt s a can deduce P W b in a similar manner to above. The corresponding analysis is found in [33], but we do not present it here as similar insights are deduced regarding the advantage of directional communications.…”

There has been recent interest in the development of untethered sensor nodes that communicate directionally via free space optical communications for mission critical settings in which high-speed link guarantees in hostile environments are needed. Directional wireless optical sensor networks have the potential to provide gigabits per second speeds for relatively low power consumption enabling bursty traffic and longer network lifetimes. In randomly deployed sensor settings, the crucial steps of ad hoc route setup and node localization are not only nontrivial, but also vulnerable to security attacks. In response to these challenges, this paper proposes a lightweight securityaware integrated routing and localization approach that exploits the benefits of link directionality inherent to wireless optical sensor networks. The circuit-based algorithm that makes use of directional routing loops, called SIRLoS, leverages the resources of the base station and a hierarchical network structure to identify topological information and detect security violations in neighborhood discovery and routing mechanisms. We study the performance of the SIRLoS algorithm demonstrating that reduced localization error, routing overhead, and likelihood of attack in various contexts are possible within lightweight computational constraints.

INTRODUCTIONT HE LAST few decades has seen a substantial transformation of wireless networking technologies leading to the recent interest in the integration of computation, communications and sensing mechanisms for low cost untethered device development. There is currently also an active interest in enabling a tighter coupling of this sensor networking technology to the physical world through actuation. This would lead to numerous new applications including smart vehicles, autonomous disaster exploration, and the surveillance and control of critical infrastructure. In such life-critical contexts designing for safety often translates to ensuring communication system security and device "awareness". For example, in disaster exploration, autonomous agents must have the ability to acquire and transmit sensed multimedia data such as temperature and video signals as well as identify their location in order to provide essential information to first responders.Research in mission critical networks (MCNs) addresses such challenges through the development of mechanisms Manuscript received

“…Exploiting the security benefits of link directionality, Okorafor [ 14 ] introduced a novel light-weight circuit-based, secure and integrated routing and localization paradigm within the FSOSNs. This scheme leverages the hierarchical cluster-based organization of the network, and the directionality of the links to deliver enhanced security performance including per hop and broadcast authentication, confidentiality, integrity and freshness of routing signals.…”

Recently, free space optical sensor networks (FSOSNs), which are based on free space optics (FSO) instead of radio frequency (RF), have gained increasing visibility over traditional wireless sensor networks (WSNs) due to their advantages such as larger capacity, higher security, and lower cost. However, the performance of FSOSNs is restricted to the requirement of a direct line-of-sight (LOS) path between a sender and a receiver pair. Once a node dies of energy depletion, the network would probably suffer from a dramatic decrease of connectivity, resulting in a huge loss of data packets. Thus, this paper proposes a reconfigurable routing protocol (RRP) to overcome this problem by dynamically reconfiguring the network virtual topology. The RRP works in three phases: (1) virtual topology construction, (2) routing establishment, and (3) reconfigurable routing. When data transmission begins, the data packets are first routed through the shortest hop paths. Then a reconfiguration is initiated by the node whose residual energy falls below a threshold. Nodes affected by this dying node are classified into two types, namely maintenance nodes and adjustment nodes, and they are reconfigured according to the types. An energy model is designed to evaluate the performance of RRP through OPNET simulation. Our simulation results indicate that the RRP achieves better performance compared with the simple-link protocol and a direct reconfiguration scheme in terms of connectivity, network lifetime, packet delivery ratio and the number of living nodes.
