A survey on position-based routing in mobile ad hoc networks
TLDR
An overview of ad hoc routing protocols that make forwarding decisions based on the geographical position of a packet's destination and previously proposed location services are discussed in addition to position-based packet forwarding strategies.Abstract:
We present an overview of ad hoc routing protocols that make forwarding decisions based on the geographical position of a packet's destination. Other than the destination's position, each node need know only its own position and the position of its one-hop neighbors in order to forward packets. Since it is not necessary to maintain explicit routes, position-based routing does scale well even if the network is highly dynamic. This is a major advantage in a mobile ad hoc network where the topology may change frequently. The main prerequisite for position-based routing is that a sender can obtain the current position of the destination. Therefore, previously proposed location services are discussed in addition to position-based packet forwarding strategies. We provide a qualitative comparison of the approaches in both areas and investigate opportunities for future research.read more

Spray and wait: an efficient routing scheme for intermittently connected mobile networks
TL;DR: A new routing scheme, called Spray and Wait, that "sprays" a number of copies into the network, and then "waits" till one of these nodes meets the destination, which outperforms all existing schemes with respect to both average message delivery delay and number of transmissions per message delivered.

Efficient routing in intermittently connected mobile networks: the multiple-copy case
TL;DR: A detailed exploration of the single-copy routing space is performed in order to identify efficient single- copy solutions that can be employed when low resource usage is critical, and can help improve the design of general routing schemes that use multiple copies.

Ad-hoc on-demand distance vector routing
C.E. Perkins,E.M. Royer +1 more
TL;DR: An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure and the proposed routing algorithm is quite suitable for a dynamic self starting network, as required by users wishing to utilize ad- hoc networks.

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers
TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.
