Trust Based Secure Routing in Delay Tolerant Networks

There is a growing need for secure and robust networks that function in austere environments or with nodes that have limited resources. The prime example is Delay Tolerant Networks that have military, first response, infrastructure failure and vehicle applications. This class of networks requires the modification of traditional routing and security protocols, such as TCP/IP or the use of certificate revocation servers, to effectively transmit a message from source to destination in a secure manner. There are multiple trust and routing schemes proposed for use in Delay Tolerant Networks. Here,…

Cost-Aware SEcure Routing (CASER) Protocol Design for Wireless Sensor Networks

Cost-Aware SEcure Routing (CASER) Protocol Design for Wireless Sensor Networks Lifetime optimization and security are two conflicting design issues for multi-hop wireless sensor networks (WSNs) with non-replenishable energy resources. A novel secure and efficient Cost-Aware SEcure Routing (CASER) protocol is proposed to address these two conflicting issues through two adjustable parameters: energy balance control (EBC) and probabilistic-based random walking. The energy consumption is severely disproportional to the uniform energy deployment for the given network topology, which greatly reduces the lifetime of the sensor networks. To solve this problem, an efficient…
