We need directional Motes! … or the next generation of sensor networks.

This talk explores the need for directional motes in sensor networks. It discusses the problem of network diameter and presents a solution involving the addition of directional motes. By incorporating these motes, the diameter of the network can be significantly reduced. This talk may inspire researchers to change their focus, become theoreticians, or delve into hardware development.

  3. The Theory • Diameter is (roughly) O(√n) in the natural case of n = O(1/r2) (needed to ensure coverage). • Problem: even adding motes does not reduce diameter! • We show that if n = Ω(1/r2 log(1/r)) and N = Ω(1/R2 log(1/R)) then the diameter is O(1/R+R/r). • If we choose 1/R = √1/r the diameter is reduced from (roughly) √n to n1/4 by only adding N ≈ √n directional motes. • Ergo: We need directional motes!
