TL;DR: A novel lightweight distributed algorithm is introduced for speckled computing and simulation results are presented to determine the goodness of the algorithm for different parameters, and the algorithm was successfully ported to a hardware prototype of the speck called the ProSpeckz.
Abstract: Speckled computing (Arvind, DK and Wong, KJ, Proc IEEE Int Symp on Consumer Electronics, p219-23, 2004) is an emerging technology in which data is sensed in minute (eventually one cubic millimetre) semiconductor grains called specks Information is extracted in situ from each speck and is exchanged and processed in a collaborative fashion in a wireless network of thousands of specks, called a specknet Specks are not assumed to be static, and therefore estimating and maintaining the logical location of the mobile specks in a network is essential for a number of speckled computing and sensor network applications A novel lightweight distributed algorithm is introduced for this purpose and simulation results are presented to determine the goodness of the algorithm for different parameters, The algorithm was also successfully ported to a hardware prototype of the speck called the ProSpeckz The problems and issues of porting the algorithm onto such a resource-constrained hardware platform are discussed Finally, the paper concludes with plans to improve the algorithm

TL;DR: Arvind et al. as mentioned in this paper presented new challenges for the design of communication protocols for specknets, in which each speck is modest in terms of energy, storage and computational resources.
Abstract: Speckled computing (D.K. Arvind et al., 2004) is an emerging technology in which data is sensed and processed in small (around 5 /spl times/ 5 sq. millimeter) semiconductor grains called Specks. A dense and non-static wireless network of thousands of these specks - called a Specknet - collaborates to extract information from the data. Speckled computing demands requirements of wireless communications in excess of typical mobile ad-hoc networks (MANET) and sensor networks. This paper presents new challenges for the design of communication protocols for specknets, in which each speck is modest in terms of energy, storage and computational resources.

TL;DR: In this paper, two responsive environments were implemented using prototype speck technology called Prospeckz: a behaviourally-responsive suite of furniture, and an emotionally-responsive mood cloud.
Abstract: Two responsive environments were implemented using prototype speck technology called Prospeckz: a behaviourally-responsive suite of furniture, and an emotionally-responsive mood cloud. The paper describes their implementation and their deployment at an arts exhibition in Edinburgh in December 2004. The results of a survey of the visitors to the exhibition are analysed and light is cast on issues, which may be significant towards the acceptance of responsive environments in people's everyday lives.
