“…The cost of inquiry is significant, considering the fact that recent cell phones such as LG chocolate and Motorola MOTOKRZR K1m are equipped with less than 900mAh battery. We propose a simple solution to reduce the frequency of inquiry by using the concept of sociological orbits [38]. Sociological orbits are probabilistic mobility models where nodes move between a set of hubs, e.g., subway stations or bus stops.…”

Abstract-Using handheld devices such as cellular phones and smart phones for personal entertainment has become commonplace in today's lifestyle. Virtually all of these devices are equipped with Bluetooth technology that can be used to distribute entertainment contents such as music and movie clips. Mobile users can download content from the opportunistically available infrastructure (e.g., Digital Billboards) as well as direct Peer-toPeer (P2P) collaboration which significantly increases content availability/coverage. P2P content distribution protocol design is heavily influenced by the characteristics of Bluetooth, which is the main departure from Internet-based content distribution. However, little has been done to understand the performance of overall Bluetooth operations, ranging from peer discovery to data downloading, in dynamic environments with mobility, interference, and different Bluetooth versions/chipsets. In this paper, we first perform extensive experiments to measure the performance of Bluetooth in dynamic environments. We find that Bluetooth-based content distribution faces several challenges such as time/energy consuming resource discovery and limited bandwidth even with the enhanced features of the latest Bluetooth version. We then propose strategies that can effectively improve the performance of resource discovery and downloading phases. Our simulation and experimental results document the improvements obtained with our proposed techniques.

“…Such mobility models include random waypoint(RWP), random walk(RW) and random direction(RD) [16]. It has been recently widely acknowledged that random-based mobility is unrealistic and that routing schemes are frequently discussed on sociologicallyorganized mobility models, which are studied in the context of buses [26], taxi [21], sociological orbit [11,12] and pedestrians [5]. Community-based mobility is also proposed by [23], but it is basically random direction mobility which hierarchically defined.…”

Many message routing schemes have been proposed in the context of delay tolerant networks (DTN) and intermittently connected mobile networks (ICMN). Those routing schemes are tested on specific environments that involve particular mobility complexity whether they are random-based or sociologically organized. We, in this paper, propose community structured environment (CSE) and mobility entropy to discuss the effect of node mobility complexity on message routing performance. We also propose potential-based entropy adaptive routing (PEAR) that adaptively carries messages over the change of mobility entropy. According to our simulation, PEAR has achieved high delivery rate on wide range of mobility entropy, while link-state routing has worked well only at small entropy scenarios and controlled replicationbased routing only at large entropy environments.

“…The prediction-based schemes (e.g SOLAR [16]) try to reduce message overhead and buffer contention through forwarding messages only to nodes with high delivery probability. However, due to the disconnected nature of the network, it may take a very long time before every node receives the delivery probabilities of other nodes.…”

Selective Message Forwarding in Delay Tolerant Networks

Abstract-It is challenging to deliver messages in a network where no instant end-to-end path exists, so called Delay-Tolerant Network (DTN). Node encounters are used for message forwarding. In this paper, we propose a DTN routing protocol SMART. SMART utilizes the travel companions of the destinations (i.e. nodes that frequently meet the destination) to increase the delivery opportunities while limiting the message overhead to a bounded number. Our approach differs from a few related work in that it does not propagate node encounter history nor the delivery probabilities derived from the encounter history. In SMART, a message source injects a fixed number of copies of the message into the network to forward the message to a companion of the destination, which only forwards the message to a fixed number of the destination's companions. Our analysis and simulation results show that SMART has a higher delivery ratio and a smaller delivery latency than the controlled opportunistically-forwarding schemes and has a significantly smaller routing overhead than the pure flooding schemes.
