Routing is the foremost issue in mobile ad hoc networks (MANETs) and sensor networks. To guarantee delivery and improve performance, most position-based routing protocols are based on face routing, which requires the underlying network to be a planar graph. Localized planar graph construction requires the radio model to be a unit disk graph and it is only applicable to two-dimensional networks....

Most previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located. The significant communication overhead can be avoided if the routing strategy is changed. We propose that the source node issues several search 'tickets' (each ticket is a 'short' message c...

Ad-Hoc networks are decentralized wireless networks. A fundamental problem in Ad-Hoc networks is finding a secure and correct route between a source and a destination efficiently. The need for scalable and energy efficient routing protocols, along with the availability of small, inexpensive and low power positioning instruments, results in making position-based routing protocols a promising cho...

With resent advances of Deep Sub Micron technologies, the floorplanning problem is an essential design step in VLSI layout design and it is how to place rectangular modules as density as possible. In this paper, we propose a novel constraint driven floorplanning technique based on Genetic Algorithm (GA). Many works have done for the floorplanning problem using GA. However, no studies have ever ...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Position based routing protocols are becoming popular due to advancement and availability of GPS devices. On...

In this paper, we propose a combination between a routing protocol and Hierarchical Location Service (HLS) that we denote Hybrid Routing and Hierarchical Location Service (HRHLS). HLS and a routing protocol used to be combined in the original work with a direct method, i.e. the routing protocol takes care of routing packets and HLS is called to get the destination position when the target node ...

The correctness of the position is fundamental for position-based services. Previously proposed position verification schemes require an infrastructure, or the existence of a one-hop direct communication between the prover and the verifier. These schemes are less feasible in infrastructure-less networks where communication is achieved via multiple hops, such as mobile ad hoc networks. In this w...

In mobile ad hoc networks (MANETs), the network topology changes frequently and unpredictably due to the arbitrary mobility of nodes. This feature leads to failures and route reconstructions, which causes an increase in the routing control overhead. Effective routing protocol needed to developed or modifying existing one. Protocols can be divided into topologyand position-based protocols but th...

Minimizing Energy consumption is considered as one of the most important principles in the development of routing protocols for Wireless Sensor Networks (WSN). In this study, we propose a Location based Energy-Aware Reliable routing protocol (LEAR) for WSN based on sensor position and clustering. Geographical routing protocols are efficient and convenient for optimum energy consumption and band...
