In a future internet of things, an increasing number of every-day objects becomes interconnected with each other. Current network solutions are not designed to connect a large number of co-located devices with different characteristics and network requirements. To cope with increasingly large and heterogeneous networks, this paper presents an 'incentive driven' networking approach that optimizes the network performance by taking into account the network goals ('incentives') of all individual devices. Incentive driven networking consists of the following steps. First, devices dynamically search for co-located devices with similar network preferences and hardware and/or software capabilities. Next, if such devices are found, communities consisting of interconnected objects with similar network expectations are formed on an ad-hoc basis. Due to the similarities between the involved devices, it is easier to optimize the network performance of each individual community. Finally, different communities can cooperate with each other by activating and sharing (software or hardware) network resources. The paper describes which (future) research is needed to realize this vision and illustrates the concepts with a number of simple algorithms. Through an experimental proof-of-concept implementation with two networks of resource-constrained embedded devices, it is shown that even these simple algorithms already result in improved network performance. Finally, the paper describes a large number of example use cases that can potentially benefit from our innovative networking methodology.

“…All terminals are assumed to be synchronized and all packets have equal length. Moreover, we assume that packet arrivals at each terminal are independent and follow a Bernoulli process [5] [7]. Specifically, each terminal generates a new packet with probability during each time slot, and the probability of no packet generation is 1 − .…”

“…In [5], a fixed relay/wireless router utilizes the idle time slots available in a TDMA frame and two corresponding MAC protocols are designed to assist packet retransmissions. Although this method improves packet retransmissions when idle time slots are available, it becomes less effective when the traffic load is high (few idle slots are available).…”

Abstract-Cooperative diversity is an effective technique for transmission performance improvement over fading channels. In this paper, through the use of a virtual antenna array, a time division multiple access (TDMA) based cooperative media access control (MAC) protocol, Cooperative TDMA (C-TDMA), is proposed to enable cooperative transmissions in Rayleigh fading channels to improve the probability of correct packet reception and system throughput. A C-TDMA throughput expression is derived using a Markov chain model. Numerical results show that the throughput of conventional TDMA can be improved by over 40% through the use of the cooperative MAC designs.

“…For example, in [10] two MAC protocols are presented that use a relay node to store the packets that failed transmissions in previous time slots and attempts to retransmit them in an empty time slot. As a second example, when using opportunistic networking [11], the general idea is that, in the absence of a fixed infrastructure for connectivity, data exchanges could take place using the connection opportunities that arise due to impromptu encounters with other devices.…”

Abstract-In a future 'internet of things', an increasing number of every-day objects are connected with each other. Nowadays, connectivity between these devices is supported by assigning each device to an existing (wireless) network. However, these networks do not take into account the individual needs of these devices, even though all these devices are very different in terms of application requirements and hardware capabilities. Moreover, multiple existing networks are often configured independent from each other without any interaction. As an alternative, this paper proposes and discusses a methodology that more efficiently supports network cooperation between heterogeneous devices. The paper argues for autonomously created communities of similar devices, that are able to negotiate with different co-located communities to further optimize their network performance. Different communities engage in cooperation by activating network services, but only when the end result is beneficial for all involved communities. In this paper, the concepts and advantages of this approach are discussed. In addition, a methodology is explored that is able to realize these concepts. Finally, based on this methodology, possible network solutions are presented, remaining challenges are listed and future research opportunities are identified.
