The flexibility and mobility of Mobile Ad hoc Networks (MANETs) have made them increasingly popular in a wide range of use cases. To protect these networks, security protocols have been developed to protect routing and application data. However, these protocols only protect routes or communication, not both. Both secure routing and communication security protocols must be implemented to provide full protection. The use of communication security protocols originally developed for wireline and WiFi networks can also place a heavy burden on the limited network resources of a MANET. To address these issues, a novel secure framework (SUPERMAN) is proposed. The framework is designed to allow existing network and routing protocols to perform their functions, whilst providing node authentication, access control, and communication security mechanisms. This paper presents a novel security framework for MANETs, SUPERMAN. Simulation results comparing SUPERMAN with IPsec, SAODV, and SOLSR are provided to demonstrate the proposed frameworks suitability for wireless communication security.

Recent advances in the relevant technologies of contemporary wireless sensor nodes has motivated a growth in the deployment of wireless sensor networks (WSN) for commercial, non-commercial and research applications. In the aforementioned applications, it is often prudent to frustrate unauthorised wireless communications with WSN nodes. A symmetric cryptographic technique referred to as Authenticated-Encryption with Associated-Data (AEAD) can be employed to provide secure communication channels for authorised nodes in the specified WSN by providing both confidentiality and integrity security services to transmitted data. This paper introduces an adjustable one-pass block cypher-based AEAD construct that is named CypherCodex. CypherCodex is designed to operate in energy constrained wireless sensor nodes and WSN time-critical applications. CypherCodex is benchmarked in comparison against appropriate block cypher-based AEAD constructs. The results of the software simulation benchmark indicate that CypherCodex depending on its operational parameters; exhibited better performance regarding data processing throughput and processing efficiency for practical transmitted WSN data packets.

This paper presents a novel extension to the Consensus-Based Bundle Algorithm (CBBA), which we have named Cluster-Formed Consensus-Based Bundle Algorithm (CFCBBA). CF-CBBA is designed to reduce the amount of communication required to complete a distributed task allocation process, by partitioning the problem and processing it in parallel clusters. CF-CBBA has been shown, in comparison with baseline CBBA, to require less communication when allocating tasks. Three key aspects of task allocation have been investigated, (a) the time taken to allocate tasks, (b) the amount of communication necessary to satisfy the requirements of distributed task allocation algorithms such as CBBA, and (c) the efficiency with which a collection of tasks (a mission) is completed by a group of robots (a collective).

A zone based systems design framework is described and utilized in the implementation of a message authentication code (MAC) algorithm based on symmetric key block ciphers. The resulting block cipher based MAC algorithm may be used to provide assurance of the authenticity and, hence, the integrity of binary data. Using software simulation to benchmark against the de facto cipher block chaining MAC(CBC-MAC) variant used in the TinySec security protocol for wireless sensor networks and the NIST cipher block chaining MAC standard, CMAC; we show that our zone based systems design framework can lead to block cipher based MAC constructs that point to improvements in message processing efficiency, processing throughput and processing latency.
