Position location (PL) has been an important and motivating criterion in position-based routing protocols which will reduce routing overhead. Several PL technologies such as Global Positioning System (GPS), the active badge system, the bat system and the cricket compass system have been proposed. GPS technology is very useful outdoor but quite ineffective indoors because walls in buildings block GPS transmissions. Other systems mentioned above are hardware-based which require additional devices for signal transmission and this will significantly incur additional cost of installation and maintenance. In this paper, the development of a GPS-free, simple self-positioning system to be implemented in MANET are presented where the node itself determines its location from hello message signals received that are being broadcast at intervals from specifically identified stationary nodes. Location of all nodes will be based on a global coordinate system which will provide a simpler routing task in any position-based routing protocol. The proposed system will be economically developed since the hardware required are laptops or PDAs with a standard IEEE 802.11 wireless LAN card which will have a relative large transmission coverage compared to Bluetooth and infrared signals.

    • "In [9], the authors proposed schemes for tracking their positions by using pilot signal strength measurements from neighboring nodes and tracking mobility by using an extended Kalman filter preceded by an efficient averaging filter. In [10], L. A. Latiff et al proposed self-location solution, in which, HELLO messages including strength measurement parameters is conveyed among nodes and pre-determined nodes in a area, thus the locations of node will be calculated based on the measurements extracted from that messages. In [11], a self-configurable positioning technique for multihop wireless networks is proposed, which based on a Euclidean distance estimation model and a coordinates establishment scheme. "

    ABSTRACT: Opportunistic network (ON) is particular type of delay-tolerant network. ON takes advantages of the broadcast nature of wireless medium to improve the transmission quality and range. In GPS-free environments, positioning is resolved by solutions basing on self-positioning, cooperative localization... However, major disadvantage of these methods lies in requiring strict synchronization between each pair of sender and receiver. In this paper, we propose a novel tracking the mobility scheme of nodes based on Time-Reversal (TR) technique without requiring strict synchronization and a new forwarding strategy is inferred. We simulate the processes in operation of new forwarding strategy basing on proposed mobility tracking. The simulation results show that applying TR technique for tracking mobility of nodes is efficient in finding forwarding nodes. And these results also indicate that there is a predicted duration time which the probabilities of sending packets to destinations has high value. Therefore, we can anticipate the optimal size of packets is used for the current state of the network.

    • "This paper focuses on the localization using radio signals. The localization algorithm use is triangulation which is suitable for indoor environment [3]. For this project Wireless Local Area Network (WLANs) is built by attaching a device called the access point (AP) to the edge of the wired network. "

    ABSTRACT: Representation of indoor 3D location tracking had been an advantage to globally supported to track the mobile unit everywhere, even in different level of building. Our main focus is presenting development of indoor 3D location tracking to replace the existing 2D location tracking. The 2D location tracking mechanism only supports tracking the mobile unit position in the same level and provides handover or device switching. If the users need to go to another level, user will have to disconnect the connection. The development of the system that has a location tracking mechanism responsible to track the position of the mobile unit (such as laptop and PDA). In this paper, the system running in IPv4 framework and set up as a read test bed. The proposed location tracking will be based on Received Signal Strength Indicator (RSSI). The 3D location tracking system will be purely software based with minimum hardware dependent.

    • "where dðS; NÞ is the one-hop distance between source node S and destination node N. In this study, this distance is assumed to be fixed. However, if the sensor node is mobile, the distances can be calculated from the signal strength as shown in [22] [23]. If the velocity is high, the packet has a high probability to arrive before deadline and thus ensure real-time communication. "

    ABSTRACT: Wireless sensor network (WSN) is a wireless ad hoc network that consists of very large number of tiny sensor nodes communicating with each other with limited power and memory constrain. WSN demands real-time forwarding which means messages in the network are delivered according to their end-to-end deadlines (packet lifetime). This paper proposes a novel real-time routing protocol with load distribution (RTLD) that ensures high packet throughput with minimized packet overhead and prolongs the lifetime of WSN. The routing depends on optimal forwarding decision that takes into account of the link quality, packet delay time and the remaining power of next hop sensor nodes. The proposed mechanism has been successfully studied and verified through simulation and real test bed implementation.
