An energy efficient multimodal Wireless Video Sensor Network with eZ430–RF2500 modules

Resource management in cooperative multi‐agent networks through self‐triggering

“…Since the nodes in our experiments are within 10 m from each other, hardwarespecific sporadic losses of messages are negligible [34]. Nevertheless, an increase in lost messages can easily be compensated for according to Remark 4. As predicted by (33), the graphs in Figs. 9a and b are rather non-linear with vertical and horizontal asymptotes; hence, considerable decreases of intertransmission intervals may not significantly improve performance while the corresponding expected lifetimes may be significantly shortened (and vice versa).…”

“…However, we point out that κ is a function of L ρ , agent dynamics and the selected decentralised control law. In order for (33) to be finite, the following needs to hold τ ρ ∈ 0, ln κ k (34) which is in line with Theorem 1. Let us measure the MAN performance in terms of the time to reach (i.e.…”

“…In addition, these nodes are quite affordable and have modest energy requirements [33]. Each eZ430-RF2500 node (Fig.…”

“…Apparently, an increase in the control gain k decreases τ max ρ . From (48) and (33), one concludes that, for a fixed k, the greater τ ρ (i.e. greater K and γ ) becomes, the smaller the rate of convergence towards the MAN objective becomes and the closed-loop system becomes more susceptible to disturbances/noise.…”

“…more frequent information exchange). Nevertheless, a decrease in k might impair the MAN performance and disturbance rejection because of k α in (33). Therefore one needs to carefully balance between performance and energy needs.…”
