The advent of wireless mesh networks has augmented the provision of internet access at discounted tariffs. On the contrast, lossy links and interferences give way to depraved quality of service. Even at this standpoint a wireless mesh network affords to deliver reliable output using novel approaches like Anypath routing that enrich the level of optimality associated with the routing techniques. Anypath routing is an elite approach cited in vision to enhance performance in the wireless network framework characterized by its unreliable nature. This paper seeks through every technique available on hand to find the ones catering high optimality. The paradigms and algorithms embodied in this particular survey range from the discursive single rate routing to the prominent multi rate routing variants.
