“…This process can introduce path stretch [5] as nodes bypass the topological view of the supporting network and instead forward information based on the overlay topology. It is this property that makes overlay-based DHTs unsuitable for sensor network deployments; however, there is ongoing work to make adaptations to improve the use of overlay protocols in wireless environments [6].…”

“…There are three main approaches to building a DHT in wireless sensor networks: 1) overlay DHT, where the address space is built on top of an existing converged protocol [6]; 2) virtual, where nodes construct a tree [8]; and 3) physical location-based schemes [4], which map N-dimensional spaces onto the actual or estimated physical location of the node.…”

“…ScatterPastry [6] can be implemented using either overlay or underlay DHT. When using the overlay mechanism, there must be an existing Layer 2 frame-forwarding mechanism in place on the network, such as destination-sequenced distance vector (DSDV) [11].…”

The Internet of Things (IoT) will result in the deployment of many billions of wireless embedded systems creating interactive pervasive environments. It is envisaged that devices will cooperate to provide greater system knowledge than the sum of its parts. In an emergency situation, the flow of data across the Internet of Things may be disrupted, giving rise to a requirement for machine-to-machine interaction within the remaining ubiquitous environment. Geographic Hash Tables (GHTs) provide an efficient mechanism to support fault-tolerant rendezvous communication between devices. However, current approaches either rely on devices being equipped with a GPS or being manually assigned an identity. This is unrealistic when the majority of these systems will be located inside buildings and will be too numerous to expect manual configuration. Additionally when using GHT as a distributed data store, imbalance in the topology can lead to storage and routing overhead. This causes unfair work load, exhausting limited power supplies as well as causing poor data redundancy. To deal with these issues we propose an approach that balances graph-based layout identity assignment, through the application of multi fitness genetic algorithms. Our experiments show through simulation that our multi fitness evolution technique improves on the initial graph-based layout, providing devices with improved balance and reachability metrics.

Abstract-Wireless sensor networks (WSNs) have become pervasive and are used for a plethora of applications and services. They are usually deployed with specific applications and services; thereby precluding their re-use when other applications and services are contemplated. This can inevitably lead to the proliferation of redundant WSN deployments. Virtualization is a technology that can aid in tackling this issue. It enables the sharing of resources/infrastructures by multiple independent entities. This position paper proposes a novel multi-layer architecture for WSN virtualization and identifies the research challenges. Related work is also discussed. We illustrate the potential of the architecture by applying it to a scenario in which WSNs are shared for fire monitoring.

“…Previous research has focused on using DHTs within WSNs, including solutions like ScatterPastry [17], Virtual Cord Protocol (VCP) [18], Geographic Hash Table (GHT) [19], and Chord for Sensor Networks (CSN) [20]. The difference between previous research and our architecture is that our study does not use P2P technologies for communication within a single WSN but rather for interconnecting separate WSNs.…”

Using RELOAD and CoAP for wide area sensor and actuator networking

In this article, we propose a new architecture for wide area sensor and actuator networking. The architecture is based on combining two protocols being standardized by the Internet Engineering Task Force, REsource LOcation And Discovery (RELOAD) and Constrained Application Protocol (CoAP). To integrate CoAP and RELOAD, we introduce a CoAP application usage for RELOAD. The architecture provides a decentralized peer-to-peer rendezvous service for CoAP nodes in Wireless Sensor Networks (WSNs). Our architecture also enables a peer-to-peer federation of geographically distributed WSNs. This is supported by proxy nodes that are part of the WSN but also connect to a RELOAD overlay network via cellular Internet access. Due to the use of RELOAD, the system does not need to rely on centralized services such as DNS service discovery (DNS-SD) or central resource directories to discover sensors and resources. Other features of the architecture include integration to web, self-organization, scalability, and robustness. We evaluate the proposed architecture through simulations and real-life measurements, and compare its performance to a traditional client/server architecture.
