This book constitutes the thoroughly refereed post-conference proceedings of the 6th International Workshop on Algorithms for Sensor Systems, Wireless Ad Hoc Networks, and Autonomous Mobile Entities, ALGOSENSORS 2010, held in Bordeaux, France, in July 2010. The 15 full papers and two brief announcements were carefully reviewed and selected from 31 submissions. The workshop aimed at bringing together research contributions related to diverse algorithmic and complexity-theoretic aspects of wireless sensor networks. In 2010 the focus was extended to comprise also contributions about related types of networks such as ad hoc wireless networks, mobile networks, radio networks and distributed systems of robots.
