Algorithm 1 Circular Motion of MSs with Varied Velocity Algorithm

Initialize all the parameters; Round = 0; Static sinks computes the velocities of MSs based on Equation (30); MSi Starts to move in predetermined circular path from position (((2j-1)(d/2)), 0) Turn Round = Turn Round +1; J = 1;// sector number Stops at (((2j-1)(d/2).cos(ϴ/2) + Xcenter), ((2j-1)(d/2).Sin(ϴ/2) + Xcenter)); //MS stops at the bisector of sectors MS sends a Hello packet to the nearest CH; CH sends a data packet to the MS //data packet contains corona number, sector number and waiting time parameter; MSi Computes the sojourn time in Cluster(i, j) based on Equation (30); MS propagates Hello packets; // Hello packet contains of position of MS and cluster id the MNs which are located in the cluster which is mentioned in received packet will connect to MS; Set timer = ST(i,j,Round); While timer > 0 do CH Temporarily stops its operations; MSi aggregates the data packets of nodes belonging Cluster (i, j); MSi receives the data packets from CH (i-1, j) and nodes belonging Cluster (i, j); Check timer; End while J = j + 1; MSi Computes its velocity {MSi | 1 < I ≤ k} based on Equation (30); MSi Starts to move; Check the current position; If current position = (((2j-1) (d/2)), 0); // when the angle of position of MSs is 0. Go to 5; End If Go
