“…So to minimize the BER interferes density should be low in high interference environment. From [10] and [12] MPR selection algorithm [18] 10 -7 at 20 dB up to 50 nodes from base MPR selection BER decrease packet delivery ratio increase this improves the through put.…”

“…In this minimization route BER is 10 -15 at 1 mW on 10 nodes /m 2 and 10 -20 route BER from Friis model at transmitted power of 1 µW for 10 nodes /m 2 . To enhance the optimum link state routing quality of service authors approach heavily relies on BER matrix and allows to increase Packet Delivery Ratio (PDR) [18]. Selecting good links during the MPR selection is not enough as the routing protocol does not provide any guarantee to use good links.…”

ABSTRACT:Over the last decade, a large number of pioneering works have provided foundations for both theory and applications of Wireless Ad hoc Networks (WLAN). As ad hoc technology is becoming the demand of present and future trends that needs for a reliable communication link having minimum BER and power. This review work presents the impact of mobility, and energy efficiency and clustering on optimization of Bit Error Rate (BER) and power as well as on throughput. An analysis review is made on Network coding scheme to optimize BER and throughput. And finally how these factors vary in WLAN is discussed in conclusion.

“…But it implies that routing algorithms are based on a subset of network links. This MPR mechanism may lead to a bad network capacity, since a node have a partial view of the network [2]. This may result in low Packet Delivery Ratio (PDR) and important endto-end delay due to retransmissions.…”

“…Link and then path reliability is taken into account in the all sub-processes of routing table calculation. Respecting the overall structure of the original MPR selection [1], our earlier BER-based MPR selection mechanism, presented in [2], mainly, considers that a 2-hopsneighbor is covered by the 1-hop-neighbor (direct neighbor) that provides the best route in term of BER.…”

The issue of Quality of Service (QoS) in wireless communications remains. To guarantee QoS, routing protocols plays an important role. Several routing approaches are proposed. Taking into account adequately link quality in all the processes concerned by route choice is tricky. In this paper,we focus on Optimized Link State Routing (OLSR) protocol, a well known Mobile Ad Hoc NETwork routing protocol. Route selection process in OLSR protocol has many components. QoS selection approach must take into account efficiently all main components of this process. Unless many works interest to the improvement of MPR nodes selection mechanism and the estimate of shortest path with dijsktra algorithm according to various metrics, very few concern the quality of path for communications with the neighbors and second-neighbors. The shortest path calculation with dijsktra algorithm does not concern this neighborhood. In this work, in addition to taking into account link reliability in the Multi-Point Relay nodes selection process and shortest path computation, we consider the neighbors and second-neighbors (2-hops-neighbors) integration process into routing table. With our new approach, a node takes into account all route announcements and select the route with the lowest Bit Error Rate. Then, a node may use two or more hops path to communicate with its neighbors. This approach allows to improve significantly packet delivery ratio.
