Abstract: Recent interest in the Internet of Things has fueled low-power sensor network deployment in urban environments - cities, towns, and suburbs. However, unlike the deployments in the wild, urban deployments are particularly challenging due to the presence of severe cross-technology interference (CTI). IEEE 802.15.4 not only shares the 2.4 GHz ISM band with a number of wireless technologies like WiFi and Bluetooth but also with many common household appliances like microwaves that form an integral part of an urban lifestyle. It is important to design protocols that are robust to such non-deterministic CTI, support high throughput transmissions and remain scalable for different traffic patterns. In this thesis, we study three class of protocols that require different levels of synchronization: asynchronous, loosely synchronous, and tightly synchronous. Tapping on the advantages and learning from the limitations of these classes, we proposed three protocols Oppcast, Codecast, and Syncast, that address the urban deployment challenges.
