The approaches of traditional stationary sensor networks lead to bottlenecks near the sink and non-uniform depletion of energy resources from the network. These approaches also decrease the probability of successful packet delivery with an increase in the number of hops from source to sink.

However, wireless and mobile computing technologies have advanced significantly in the last decade, providing various communication possibilities for mobile elements of networks without a pre-existing infrastructure. Providing solutions to these challenges, networks with one or more mobile elements have architectural requirements different from those with static sinks, since the nodes in the network would sense data at varied sampling rates and store the packets locally, awaiting the arrival of a mobile element.

One of the significant properties of a mobile element is that connectivity to the backbone network may not be available at all times. The mobile element would be able to receive data from a set of sensor nodes before returning to an access point to transfer all of the data and empty its buffers. The likelihood of a greater latency in packet delivery increases in such a situation, and it also results in intermittent connections among nodes. The nodes must benefit from contact opportunities whenever possible and the applications must better tolerate delays.

Therefore techniques for making applications tolerant to disruptions and/or high delays are required. Opportunistic and delay-tolerant networks yield to more realistic scenarios than legacy mobile ad hoc networks.

This special issue is dedicated to current state of the art in mobile sink applications and delay tolerant network protocols.
