Hybrid Swarm-Based Geographic VDTN Routing

2021
Vehicular Delay Tolerant Network (VDTN) routing is referred to the hybridization of Delay Tolerant Networks (DTNs) with VANETs which mobilizes both knowledge-based and geography-based forwarding techniques. Numerous shortage are stated in existing VDTN routing protocols in both modes exposes such as the inaccurate location information and uncontrolled ...

Randomized 3D Geographic Routing

IEEE INFOCOM 2008 - The 27th Conference on Computer Communications, 2008
We reconsider the problem of geographic routing in wireless ad hoc networks. We are interested in local, memoryless routing algorithms, i.e. each network node bases its routing decision solely on its local view of the network, nodes do not store any message state, and the message itself can only carry information about O(1) nodes. In geographic routing

Delay-Aware Grid-Based Geographic Routing in Urban VANETs: A Backbone Approach

IEEE/ACM Transactions on Networking, 2019
Due to the random delay, local maximum and data congestion in vehicular networks, the design of a routing is really a challenging task especially in the urban environment.

Multipath geographic routing using false destinations

2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009
This paper presents FDF (False Destination Forwarding), a technique that can be adopted for multipath routing in wireless sensor networks to avoid the overhead caused by the maintenance of disjointed or partially disjointed routing paths. FDF changes the packet destination target as the packet itself proceeds along the path: this way, it does not ...

Impact of mobility on geographic routing

2008 3rd International Symposium on Wireless Pervasive Computing, 2008
A new location-based reactive multi-hop protocol, namely the e-GPSR algorithm, is tested for the use in UWB sensor networks for logistic applications. Specifically, the impact of location information errors on the algorithmpsilas performance is investigated when a Manhattan mobility model is assumed and a suitable position prediction model is ...

Geographical Region Summary Service for geographical routing

ACM SIGMOBILE Mobile Computing and Communications Review, 2001
Geographical routing requires a distributed location dissemination or location database system to provide forwarding location information. In this paper, we propose a novel location dissemination system called "Geographical Region Summary Service" (GRSS).

A Geographic Location-Based Distributed Routing System

IEICE Transactions on Communications, 2011
This paper proposes a geographic location-based distributed routing (GDR) system. GDR system is a structured distributed information lookup and routing (SDILR) system that provides information lookup, based on the geographic latitude and longitude coordinates, where each node is given the coordinates as an identifier (ID) and manages an overlay routing
