Energy consumed due to communication between the different sensor nodes can consume a significant portion of the energy. Since, the energy consumption for transmitting is a function of the distance between the communicating nodes, there have been several efforts focusing on devising routing algorithms that minimize the distance of communication. A common approach to reducing energy consumption is the use of multi-hop routing. In multi-hop routing, nodes between the source and sink nodes of the communication are used as intermediary hops in the transmission. This approach is beneficial as the energy increases faster than linear with distance of transmission. Hence, having multiple transmissions of smaller distances is more energy-efficient than a single transmission of a longer distance.

To send information from a source node to a destination node through multihop links by implementing one of the above MAC protocols, routing algorithms were proposed which take into consideration the dynamic nature of wireless networks. This section described four important multihop routing protocols: dynamic source routing (DSR), ad-hoc on-demand distance vector (AODV), optimized link state routing (OLSR), and destination-sequenced distance vector (DSDV). DSR and AODV are on-demand (or proactive) routing protocols whereas OLSR and DSDV are classified as table-driven protocols.

In this section, we have shown the comparative analysis of above-mentioned protocols with their respective methodologies followed. The merits and demerits of these routing protocols are highlighted along with the initial values and parameters used during the simulation results. The merits and demerits of the same protocols are shown in Table 2. The basic properties and network characteristics followed by the respective authors in the selected routing protocols are shown in Table 3. The different characteristics of the protocols, for example, the mobility factor of the nodes, data processing technique, and type of sensor nodes, etc are shown in the Table (Table 3). All these routing protocols are designed with a similar objective to conserve the energy of the network by implementing the multi-hop routing technique.
Three-dimensional wireless ad hoc networks with random nodes distribution
Published in International Journal of Electronics, 2021
This model considers a multi-hop routing strategy in which the intermediate nodes relay a data packet to their nearest neighbour in the direction of the destination in one or more hops until it reaches the destination node. Due to the randomness in the nodes locations, the hop and route lengths are also random and their distributions must be obtained. The CDF and PDF of both the hop length and the average route length are derived in sections 2.1 and 2.2, respectively. Then, the average number of hops in a route is obtained in section 2.3. Later these values are used in finding the system’s average link and route BER and optimal transmit power.
