Location based routing protocols are the kinds of routing protocols, which use of nodes’ location information, instead of links’ information for routing. They are also known as position based routing. In position based routing protocols, it is supposed that the packet source node has position information of itself and its neighbors and packet destination node. In recent years, many location bas...

Geographic networks use physical location as destination addresses, and forward packets topographically. These networks enable geographic and proximity-sensitive applications, unlike the current Internet naming and routing architecture. Geographic routing applied to a native network generally suffers from routing inconsistencies and inefficiencies. A geographic overlay can be incrementally depl...

Geographic routing is a scalable routing technique. However existing geographic routing protocols have several restrictions that prevent it from being applied to practical wireless and wireline networks. In this dissertation, we focus on how to apply geographic routing to practical network environments. We present two novel geographic routing protocols, namely MDT and GDV, for practical wireles...

Routing in Mobile Ad Hoc Networks (MANETs) has always remained a challenging task due to its dynamic topology and lack of centralized control. Several routing protocols have been proposed over these years starting with the traditional topology based protocols to the geographic routing protocols. The research over these years shows that the geographic routing protocols like Greedy Perimeter Stat...

routing in wireless sensor networks (wsns) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in wsns. most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

In this paper, we propose an adaptive geographic routing protocol, which is composed of two routing protocols. According to the topology of the network, the adaptive geographic routing protocol can select a suitable protocol to route a packet around a hole in the sensor network. Experimental results show that the adaptive geographic routing protocol can route a packet in a suitable path and sho...

As wireless sensor networks continue to grow in size, we are faced with the prospect of emerging wireless networks with hundreds or thousands of nodes. Geographic routing algorithms are a promising alternative to tradition ad hoc routing algorithms in this new domain for point-to-point routing, but deployments of such algorithms are currently uncommon because of some practical difficulties. Thi...

In this paper, we propose two geographic routing metrics applied to wireless mesh networks that consider the use of channel width adaptation. The proposed metrics are evaluated through simulations jointly with a next hop channel width selection algorithm. The results show that the proposed metrics and algorithm generate greater throughput values when compared with existing geographic routing me...

Geographic routing is a promising routing scheme in wireless sensor networks (WSNs), is shifting toward duty-cycled WSNs in which sensors are sleep scheduled to reduce energy consumption. However, except the connected-k neighborhood (CKN) sleep scheduling algorithm and the geographic routing oriented sleep scheduling (GSS) algorithm, nearly all research work about geographic routing in duty-cyc...
