    An IOT simulation consisting of 100 nodes will be designed on the Contiki/Cooja simulation program. The communication technologies of the nodes will be distributed equally as 33 Zigbee, 33 6LOWPAN and 33 wifi. A node will be selected as "Target/Sink". The attacks will be made to this target. Of these 99 nodes, 69 of them will do DDOS attack, 10 of them will attack sinkhole, 10 of them will be blackhole and 10 of them will attack Hello Flood. Attacks can be simultaneous or in discrete time periods. The created attacks should generate PCAP files. There is no milstone payment in the project. Payment will be made after the finished presentation of the project (such as testing via link, video submission).

The router should send the MAC ID of each individual router to the coordinator and it should be read by the Controller which is placed at the Coordinator. Just I require a setting for 1 Coordinator and 3 routers. I have formed the Mesh network as attached. But could not able to read MAC address at Coordinator. All Zibgee Modules are battery operated mode only. We dont have to connect XCTU software to every Zigbee Module.

The projects do not need to be ZigBee compliant and will not interact with any other devices. The router is to join the network started by the coordinator and needs to transmit a block of 50 bytes of raw data using emberSendRawMessage() to the coordinator every 10 seconds for the coordinator to process. The data needs to be received by the coordinator buy the processing will be done later. Having Over the air firmware updates for the router would be preferred

    Requesting two complete scenarios that can be run within OMNeT++, COA-A and COA-B (course of action). Project will contain the appropriate .ned files, code, and other dependencies necessary to successfully run both scenarios and capture end-to-end transmission times. Each COA will contain a last-hop WSN node that will transmit a signal, a gateway that will converge the ZigBee and 4G-LTE protocols; and three 4G-LTE hosts: the eNodeB, the S-GW, and the P-GW. I'm very flexible with the composition of the WSN node and all 4G-LTE hosts. However, the internal protocol stacks must be accurate. The only difference between each COA will be the composition of the gateway and the internal protocol stacks of the WSN node.

    Hi, I'm attempting to create two different converged network scenarios within OMNeT++. Each will converge a wireless sensor network protocol with the 4G-LTE UE protocol stack within a gateway. The two WSN protocols are ZigBee Pro and ZigBee IP. A last-hop WSN node would generate a ZigBee X signal that would be received by a gateway. The gateway would render the ZigBee signal to something that can traverse the 4G-LTE protocol stack and continue through the eNodeB (cell tower base station) to the serving gateway (S-GW) and onto the PDN gateway (P-GW). My goal is to run 194 transmissions through each simulated environment - 388 total - and measure the network transmission delay (end-to-end) for each. Afterward I'll perform analysis and draw conclusions....
