A critical review of Optimization MANET routing protocols

The main challenges in routing protocols are node mobility, resource constraints, error-prone channel states, and problems with hidden unprotected terminals. This article provides an overview of the protocols, their problems, ways to improve them. cell phone allows communication between two moving units via mobile stations (MS), units, landing units. term "mobile ad hoc network" (MANET) refers a group devices connecting communicating. military, law enforcement, emergency services have quickly become interested MANETS because they provide high quality service. Path loss (PL), one biggest wireless communications, can be caused by multiple reflections from obstacle or source signal being far destination on network. Multipath propagation, path loss, interference reduce network's service (QoS). best route is added router's table using dynamic protocol, alternate chosen when primary unavailable.
